Bypass proxy for FQDN with private ip addresses

We have Windows 7 with IE 11
We need this IE behavior:
"to all FQDN names that resolves to local (private) ip addresses - do not use proxy."
how can we implement this?
("Bypass Proxy Server for Local Addresses" Option don't work as needed)

Hi,
Please take a check to see if the following KB article could help here:
Internet Explorer Uses Proxy Server for Local IP Address Even if the "Bypass Proxy Server for Local Addresses" Option Is Turned On
The cause: By default, only host names are checked when the Bypass proxy server for local addresses option is turned on.
The resolution here is :
To bypass a range of IP addresses or a specific domain name, specify the addresses in the proxy exception list:
In Internet Explorer, on the Tools menu, click Internet Options.
On the Connections tab, click LAN Settings.
Click Advanced, and type the appropriate information in the
Exceptions area.
Hope this may help
Best regards

How to know whether bypass proxy for local address is enabled in browser

Can anyone help me in finding out whether the check box "bypass proxy server for local address" in Internet explorer (Tools->Internet options->Connections->LAN Settings) is enabled from java plug in.
In my applet application if that checkbox is enabled then i have to throw a message saying that the checkbox is enabled.
Thanks in Advance

We have been in discussions with Microsoft over the last few days on this issue - which is seen with Outlook 2007 versions onwards. Extract from resolution communication from Microsoft:
The issue you have raised is known as it has been reported and when you have a proxy set in Internet Explorer and “Bypass proxy settings for local addresses”, Outlook will attempt to connect to Office 365 directly – like the bypass rule would apply.
Because the direct connection is blocked in the Firewall, Outlook needs to have the connections going in Timeout before attempting to connect using the Proxy.
Your network trace proves the issue.
Microsoft have scheduled a fix for Outlook 2010 in February 2014 cumulative update. A fix for Outlook 2013 will also follow, but Outlook 2007 will not be addressed because it is in Extended Support.
There are two possible workarounds for this behaviour:
First, and I wouldn’t recommend it, is to allow Direct traffic through the Firewall to Office 365.
The advantage of this approach is that it will be done centralized and it will impact everyone immediately.
Information about the O365 IP addresses
There are two downsides to this behaviour:
1. First you need to maintain the Firewall exceptions as IP from O365 server can change without notice
2. Second, winhttp traffic may go through both proxy and direct and this can cause unforeseen behaviour.
The second approach is to use a proxy pac instead of manually setting in the proxy and the exceptions.
The advantage is that you will have centralized method to control how winhttp traffic goes and the issue will not be experienced anymore.
If a single pac does not be fit, you can configure proxy pac files for each site requirements and use an IIS server to store it.

Bypass Proxy for Local Addresses

All-
With the new 2.0 software, I am now able to connect my 3G iPhone to the WiFi network at work. The network uses an authenticated proxy to get external access. I can access external sites just fine now, but I can't see internal sites. The proxy settings on my work desktop give me the option to "bypass proxy server for local addresses".
Is there any way to do this on an iPhone?
Right now I need to make a choice between access only internal sites or only external sites.
Thanks!

While not wanting to be a total weenie, ME TOO
After a bit of searching, the best we're going to be able to do right now is use a Proxy Auto-Config (.pac) file. I'm drawn to this conclusion from combining a lot of web searches with a peek at the "iPhone and iPod touch Enterprise Deployment Guide, Second Edition" (available at http://manuals.info.apple.com/enUS/Enterprise_DeploymentGuide.pdf, or via the Apple iPhone Enterprise support page at http://www.apple.com/support/iphone/enterprise/.
Setting the PAC file using the iPhone v2.x software is pretty direct - click the little arrow next to the network you want to configure, scroll down to the bottom where the proxy settings live. Choose "Auto" and enter the Auto-config URL.
That's the good news. The bad news is that I'm not entirely sure what that entails w.r.t. using one with the iPhone software. I'm not entirely clever enough to create such a file nor am I clever enough to know how to stick such a file onto my iPhone. I'm going to run this around my local team to see what they can come up with. If they come up with a solution (and it's simple enough for me to do AND explain), then I'll post a follow-up. Until then, good luck to you AND if you figure something out feel free to share with everyone else.

Bypass Proxy for Local Addresses - Office 365 connection/ Outlook 2010

This is a strange one. Connectivity to Office 365 within our netwotk works fine although very slow for outlook 2010 client to initially connect. Once connected, it works ok. I have done a netwotk trace using netmon to see if i can identify
the reason for the slow startup (2 mins minumum for profile to load and for outlook to connect to exchange). The trace tell me that my local pc tries to make a direct connection to the office365 external IPs first, then tries the TMG proxy. Once it hits the
proxy, it kicks into life and works.
So it looks to me like it thinks the external IP address of office 365 is an internal address and spends it time trying all the ip addresses until it trys the proxy. At this point, the
Bypass Proxy Server for Local Addresses is ticked.
As soon as i untick this box, all traffic heads directly to the proxy and of course it connects like lighting. The exchange settings proxy is set in outlook for "on fast networks, connect using HTTP first, then connect using TCP/IP" (tick
is on) and the same for slow networks.
I cant for the life of me work out why it tries to connect directly to the external IPs first and not connect via TMG until i untick the
Bypass Proxy Server for Local Addresses
Would love any ideas that may assist.

Java doesn't bypass proxy for IPs using (IP-Subnet) combination ??

Dear All,
On Mac OS I am getting the below problem, I didn't tried it on Windows may be this problem may not occur there.
Problem:---
On Mac OS (Leopard).
When bypassing proxy IP in "Network Settings->Advanced...->Proxies->Bypass Hosts & Domains" field is given as IP-Subnet combination, e.g. 192.168.60/24, then in Java while trying to connect with HttpUrlConnection's connect() method, and then getting response code using HttpUrlConnection's getResponseCode() method it returns response code 407 i.e. Proxy is required. But safari works well for that,
This Java API works well when I directly give IP as 192.168.60.X it works (Java API) well.
I tried System.getProperties().setProperties("http.nonProxyHosts","192.168.60/24"), then also it doesn't works.
Please tell me any solution, suggestion or workaround or any document that tells it may not be done through Java API.

I think System.getProperties().setProperty("http.nonProxyHosts",any host name, IP with * or |) works well for Windows.
Now may be specifying the range of IPs using subnet on Mac OS (e.g.192.168.60/24) is different than on windows (e.g. 192.168.60/255.255.255.0) and therefore this fails on Mac OS. Although Java is given by Mac for its OS, but I think they didn't made any changes for this API.
Now the question is whether its a bug in Java Mac or there is some workaround present for that???
Do you have any idea that I am going right way or not??

Bypass proxy for certain sites

ls,
Can I configure BM in such a way that it bypasses itself for certain sites?
So, rather then setting the exclusion list on every PC?
For certain sites/ip-addresses we need to go out via another gateway. I have
done this now by putting the address in the IE-bypass-proxy-exclusion-list.
But I wondered if there is a way to do this centrally, on the BM-box.
Regards,
Adrie de Regt

How to set proxy for mail with Gmail account

Hi, I'm using mail and set up a Gmail pop account. My mac is behind a proxy, say 192.168.0.1:808. I set the system http and https with the above address and can browse the internet with safari. But the mail app cannot receive or send any mails from the google pop/smtp server. Do you know how I can set the proxy for mail so that it can send and receive mail? Thank you very much!

I solved this problem myself by using an app called proxifier. It's a tunneling tool I guess.

Teacher discounts for teachers with non-EDU addresses?

I've seen a number of websites say that Best Buy will price match Apple's EDU discount, specifically mentioning teachers. However, from personal experience, I know that Apple accepts non-EDU email addresses from K-12 institutions when giving their educator discount. I was informed by somebody in store at Best Buy that this deal is only available for college students with .edu email addresses. So, what's the truth? Will Best Buy price match Apple's educator discount for K-12 teachers whose institutions do not use .edu, or is this discount solely for college students and educators with .edu addresses?

Hi bbernardini,
The start of a new school year can be a busy and expensive time for students and educators alike, so wanting to take advantage of the lowest price available on the latest tech is certainly understandable. It sounds like there may be some confusion between our Low Price Guarantee and timed promotions though, so I'd be glad to shed some light on the situation.
Contrary to what you may have read elsewhere, Best Buy does not offer an official educator or student discount at this time. We are, however, able to match the price of most indentical in-stock products at local retail competitors and those shipped from and sold by select online retailers. A full list of requirements and exclusions can be found here:
BestBuy.com > Help Center > Low Price Guarantee
http://bbyurl.us/LPGFAQ
As far as our College Student Deals are concerned, these limited-time offers are indeed resricted to college-bound students. For students attending a school that does not use .edu addresses or does not provide e-mail services, a process is in place to ensure they're still able to take advantage of these promotions. Regrettably, K-12 students and educators are not eligible for these offers.
I hope this helps.

Bypassing proxy for online backup service

BM 3.8.5 w/patch 1; NW 6.5.8. I'm trying to evaluate an online backup service that doesn't support proxy servers, bizarre as that may be. Is there a way to let a program on a workstation bypass the proxy server? Also, though not germane to this forum, if anyone has any suggestions for online back that are compatible with NW and BM for a small office (under 10 computers), please chime in.

bm proxy is normally only for port 80/443, when using the forward proxy.
If this program access port 4282 and 4280/4285, then it depends how you
internet connection is set up. If bm is the default gateway for the
internal hosts and filters are applied, then you will need a filter
exception for this ports and enable dynamic nat to allow this traffic to
reach the internet. So bm proxy is not involved here.
If bm is not the default gateway, then this program will use the default
gateway defined on the PC to reach the internet and then is there where
you have to allow this traffic.

Bypassing proxy for live365 radio

Ever since I started connecting to the Internet through a proxy server (filter), I haven't been able to listen to "live365" radio stations with iTunes, either the ones programmed into iTunes or otherwise.
I have tried entering various things in the "bypass" box in Network Prefs, i.e. "live365.com", "www.live365.com", "*.live365.com" but it hasn't worked! I haven't got anything I've entered into the bypass box to work.
Any ideas, suggestions, help?

Ping failes for fqdn with two records, first record unavailable

Scenario is:
10.80.56.147 = DOWN (unavailable)
10.80.56.148 = UP (available)
bash-2.05# nslookup cscs.floreffe.se
Server: idns.floreffe.se
Address: 10.80.56.186
Name: cscs.floreffe.se
Addresses: 10.80.56.147, 10.80.56.148
bash-2.05# ping cscs.floreffe.se
no answer from cscs.floreffe.se
Why does ping fail? Why does not secondary IP address being used.

Hi,
Thanks for your answer, I have alredy disabled nscd on the system. So Solaris doesn't make some kind of check if the first IP is reachable, or saves both addresses? No. That is uncommon in most UNIX applications. The application is usually trying to operate on a single address, and uses names just to look up the address that it will use.
There are more robust applications that become more complex with dynamic name changes supported, real-time failover support, etc, but that's not an OS feature, it's handled per-application. 'ping' does not do so. TCP connections are bound to a specific address. For an application to use TCP and multiple addresses, it has to recognize the problem, then re-establish a new connection with the host, etc... This is not commonly done.
The reason for the question in the first place are the redundancy problems we have faced. If the first address isn't reachable, the second one has to be used...
What's the application? Why is the address going down? In some cases this could be handled through the use of IPMP or maybe through a load-balancer application/appliance. But that would depend on your network topology and the actual problem that you're encountering.

Bypassing proxy for certain domains

i have been advised that i can use an XML tag called <dontProxyFor> to bypass the use of a proxy server for certain host/domains in a URL-based portlet.
The node is a child node of <proxyInfo>.
i am using Portal 3.0.9.8.4 on Solaris. i have made the addition to my provider.xml but my portlets still seem to require proxy authentication ...
is this tag only support in higher versions of Portal ??
on the other hand, is there no way for us to specify a proxy user/password in the provider XML for URLservices ?

Is password security necessary for AirPort with Mac local address mode set?

Hi,
I use the Mac local access mode on my airport network and provide all Mac address that are allowed on my network. Since I specifically specify what computers are allowed on my network, why would I need to use some security protocol like WPA? Is there a risk of Mac address hijacking?
Thanks.

Hello ScootInSD. Welcome to the Apple Discussions!
Since I specifically specify what computers are allowed on my network, why would I need to use some security protocol like WPA? Is there a risk of Mac address hijacking?
Yes, MAC addresses can easily be "sniffed" and spoofed so using MAC address filtering will only thwart the most casual of network hijackers. Currently only the use of wireless encryption, either WPA or WPA2 with the stronger CCMP/AES cryptographic encryption with a strong non-dictionary password can really provide security.

Configure WRT54G Wireless Router with PUBLIC IP address and use DHCP for internal computers

Hi,I have an Internet online service with 5 public IP addresses. The router and the AP are connected to a switch. I would like to configure a WRT54G wireless router with one of this IP public Address and use DHCP (with private ip address) for the computers that will connect to the AP. As the AP is connected to the switch it is possible that other wired computers that are connected to the same switch can obtain an IP address from the DHCP ?
Thansk in advance

Thanks for your help. Please correct me if Im wrong. After connecte the equipments the way you suggestI setup a static IP address (The public IP) in the WRT54GI enable DHCP in the WRT54G with a range from 10.10.0.100 to 10.10.0.200 (as an example) The gateway is the Public IP address right ? How do I route the 10.10.0.x addresses to the public IP address. Thansk again

Creation of Server Proxy for Message interface with External Defination

Dear All,
I am getting a problem while generating a server proxy for the inbound interface . The request message used in the inbound interface is a external definition which is uploaded using a XSD file. The XSD file was supplied by a third party which is having very high complex strucuture and used lot of abstract data types in the design. When i tried to generate the proxy in the R/3 system (Transaction SPROXY) for the inbound interface i am getting following error.
Interface uses external and internal message definitions
Message no. SPRX122 *
Diagnosis
In a message interface you can use messages from different sources:
Message types and fault message types edited in the Enterprise Services Repository
Messages imported into the Enterprise Services Repository (external definitions, RFC, IDoc)
In the current message interface, message types from different sources have been used. Since messages from these different sources must be handled differently during proxy generation, such a mixture of messages within a message interface is not possible.
System Response
The interface cannot be generated.
Procedure
Change the interface definition accordingly in the Enterprise Services Repository.
Please guide me, how to generate the proxy for the interface with external defination message. I could nt geneate manullay, because it is having very high complexity and its a big structure.
Is there is any way to generate the proxy for interface with external definition
Regards
Vijayanand

Hi,
i. Import your message schemas from external definitions, or RFCs or IDocs from SAP systems. These definitions already contain data types.
ii. Create a message interface and reference the messages of the external definition, or the RFC or IDoc message.
Check this, it may help you
