Multiple WAN connections all through one router with load balancing?

I am setting up a network in my dormatory for myself and about 20 friends. about half of us have DSL connections at the moment. Is there a way to have all the DSL connections (possibly run through cheap home DSL routers) all connect into a cisco router that then acts as the gateway for our entire network? woudl it be possible for each internet request to go out over the connection that has the least load AND also be able to use some sort of load balancing, so one user cant use all of the outgoing/incoming bandwidth?
If you have any ideas please let me know

Hi Ian,
To get this working, you would either need to use something like PPP to bundle your links together or use a dynamic protocol.
In bundling the links, you could make them appear as one link, with a single IP address each end and the router takes care of distributing the load. To implement this though, you would need control of both sides of the link, or be terminating with one carrier who is happy to implement this for you.
The second is to use a dynamic protocol (such as eigrp, ospf, etc), which can build up a map of the network to router from point a to point b. For this you also need control of the link.
I can't think of another method, unless you can control the link from both sides. Your other option it to pool your money and buy a larger link or a leased line. If you bought a leased line or two, your carrier would be more than happy to talk to you about routing over that, but generally you're looking at mega bucks for that.

Webvpn GW's on one router with domain names

Hi,
I'm trying to configure multiple WebVPN gateways on one router using one front door VRF and multiple back door VRF's. Think of this like a cloud service provider with several customers using different VRFs and one Internet VRF used for the incoming connections for the remote users.
Doing so, several scenarios arise:
Using one gateway and several context with a seperate VRF for each.
Please let me know if I am wrong here:
I can only assign one trustpoint because I only have one gateway. This means that all users connecting can only use one domain name like "*.isp.com". This also implies the use of a wildcard certificate.
Using several gateways and several context with a seperate VRF for each.
I can only assign multiple trustpoints because I only have one gateway. This means that users connecting can use multiple domains name like "webvpn.clientA.com" and "webvpn.clientB.com".
I would prefer the first situation but then I run into a second problem:
There are several commands related to hostname and up till now I have not figured out which one does exactly what:
ROUTER(config)#webvpn gateway WEB_GW
ROUTER(config-webvpn-gateway)#hostname
ROUTER(config)#webvpn context CUST1_CT
ROUTER(config-webvpn-context)#gateway WEB_GW domain
ROUTER(config-webvpn-context)#gateway WEB_GW virtual-host
Is there anyone who can explain to me what exactly does what?
My personal guest is that I only need to configure the virtual-host like this" CUST1_CT -> virtual-host cust1.isp.com and CUST2_CT -> virtual-host cust2.isp.com". But I'm not sure about this and up till now I have not found any documentation that describes this very clearly.

I think for this to work correctly and be able to split traffic between the 2 ISPs, you would need to use BGP, because default is going to use one ISP or the other.
If you can use BGP, this link will help you in load shearing between multiple ISPs when you have one router.

USB connected all-in-one printers

Ok, so I know this will probably sound like the same old question answered again, but, is it possible to get full functionality from a USB connected all-in-one printer/scanner? In particular a Canon Pixma MP540. This is a printer sold from the Apple store, and so, I would have thought it would have been vetted by Apple experts. If it is not, then why is it not made more obvious in the Time capsule literature? Is it possible to rectify this by a software upgrade? Or is scanning just not possible via the USB connection? Any further light shed on this subject would be sincerely appreciated.

I also have an MP540 and was unable to setup the printer while connected to my AEBS. It could connect but the MP540 is brand new and was not available as a drop down choice. Thus I had to download a driver from the Canon site. This allowed me to get connected and setup and everything seemed fine.
However,as you say, only the printing function works. From what I can tell, this is not an Apple/Canon specific issue. It seems multi-functions just "cannot" operate normally when shared via routers. For now I just run a second USB cable over to the printer and switch it over when I want to scan. I intend to get a USB switch so I can just push a button to switch back and forth.
I too am curious if this is something that technically can be done via software. Perhaps somebody has written a utility to do this.
I should note, I though everything was fine with printing. However, it isn't, so I have started another thread because when I print various files (PDF's) they print at a zoom level and thus no longer fit properly on the page.

I have an HP Officejet 7210 all in one printer, have loaded Printer Pro to IPad, get successful test pages in the Print Pro App but can't print emails (or anything). error message is No AirPrinter found. How can I get connected?

I have an HP OfficeJet 7210 all in one printer, have loaded Printer Pro and had a successful test while in Printer Pro. When I try to print and email I get NO AIR PRINTER message, How can I connect my printer to my IPad and print emails.

Welcome to Apple Support Communities.
If you're using the Printer Pro app, you're not going to use AirPrint services.
They are not the same thing.
Are you using the 'Open In' option to get the email into Printer Pro for printing?
http://itunes.apple.com/us/app/printer-pro/id393313223?mt=8
Once installed, Printer Pro appears in the "Open In..." list on your device. This lets you print documents from Mail, Safari, ReaddleDocs and many other applications on your iPad that supports this function.
Using "Open In..." approach you can print files from many popular online storages: Dropbox, MobileMe iDisk, GoogleDocs. It just a matter of several taps to download your file via free Dropbox, iDisk or Google Docs application and send it to printer.

Connecting Apple TV to router with ethernet cable

help connecting Apple TV to router with ethernet cable

The process is transparent. I have done it before.
Now, it gives me an error message when I try Wi-Fi:
"There was a problem connecting to the network. Check your settings and try again.(5)"
When I try the ethernet cable connection it won't let me do automatic or custom.
I unplugged and replugged the Apple TV box but don't know how else to trouble shoot the lack of connectivity.

HP all-in-one C6180 with a duplexor fitted that printed double sided under Win XP but not Win 7 32bi

I have an HP all-in-one C6180 with a duplexor fitted.
I could print double sided under Wimdows XP but have now upgraded to Windows 7 32-bit.
I have installed the latest drivers for the C6180 from the HP site.
I cannot print double
sided because in Printer Properties > Device Settings > Installable Options the "Duplex unit for 2-sided printing" option is not available for Install.
Can you please provide a patch or the latest driver with the Install option enabled please.
Regards,
John Seager
{Personal Information Removed}

You may need to enable the duplexer while logged in as a user with administrative privledges. Alternately go to the Devices and Printers folder, right clisk on the C6180, Printer Properties, Security, and click the settings to allow "Manage this printer" for the user.

Recommended configuration for load balanced Portal with load balancer, multiple gateways and multiple servers.

Does anyone have a recommended network, hardware and software configuration guide for a Portal installation running with multiple gateways load balanced (ie one URL) that talk to multiple servers?

David,
We've used Resonate (software) to load balance the gateways. It allows
you to group all the gateways under 1 virtual URL and load balance the
incoming connections over each gateway depending on the rules that you
define in Resonate. Look in the SUN portal whitepapers there is one that
talks about it specifically.
As far as load balancing the calls to the portals, the gateways will
automatically load balance across all the portals that they know about
using a simple round-robin rotation. You may be able to use Resonate in
front of the portals but you may need to activate persistance within
Resonate to ensure that the user always ends up on the portal that he
established his initial connection on (if you want that), check with Sun
on this one.

HTTPS with load balancing

Hi guys,
We have a portal system with instance 08, so we typically connect to the portal using port 50800 for HTTP, and 50801 for HTTPS.
We have just created a second server node for this portal (in the config tool).
When we connect to 50800, does this automatically load balance the user to the better server? From some reading on these forums, it seemed to indicate that load balancing will only occur if I connect using port 8109. (where 09 is the instance number for the SCS of our portal)
When connecting to port 8109, we are redirected to port 50800, as I'd expect.
Question 1 - do we need to use 8109 for load balancing, or can we still use 50800?
Question 2 - If we need to use 8109, which is a HTTP port, how can we achieve load balancing with HTTPS. Is there a different port we need to use to have HTTPS with load balancing?
Question 3 - Is the creation of a second server node the best way to accomodate additional users and load on the portal system, or is there a better way to do things?
Thanks,
Michael.

Better late than never.
The load balancing you describe through the message server has its limitation. It redirects you to one of the dialog server hosts which means that any bookmarks will always point directly to a dialog server which may be down at that moment.
Access directly to a dialog server on port 50800 will sort of load balanc on the java server instances that are on that server but not on other servers.
The general recommendation is to setup an external loadbalancer and SAP Web dispatcher is a good match if the load is not very high. SAP webdispatcher will then bind up the cluster address and act as a proxy towards the dialog servers of the portal. The user will therefore only see one address. This will also work for HTTPS.

System with load balancing server

Hi All,
We are having SAP NW 7.0 Portal and back end we have R3 implemented in a cluster environment. The system object in EP have used "System with Load balancing" template; using the LOGON group and the other related parameters.
But we have some problem with the ITS and WAS parameters; since we are using some Transaction iViews.
Let me explain.. for the R3 cluster we have 2 systems PROD1.domain.ext and PROD2.domain.ext. Now in the system object in portal, how to specify the parameters for ITS and WAS parameters? Since the host name in these we need to specify a single server which defeats the basic purpose of having clustered environment.
Can any one please help in resolving this issue.
Thanks,
Sravanthi

Hi Sravanthi,
Please check the below for finding ITS and WAS parameters from backend :
For ITS - Go to SE37 >> Utilities >> Setting >> Click on ICON Right Top Corner in popup window >> Select Internet Transaction Server >> you will find the Standard Path and HTTP URL.
For WAS - Go to SE37 >> Run FM - RSBB_URL_PREFIX_GET >> Execute it >> you will find PRefix and PAth paramter for WAS.
Please refer to this may help step-by-step : How-to create a portal system for using it in Visual Composer
Hope it helps
Regards

BM clustering with load balancing

I want to implement BM clustering with load balancing according to AppNote written by Steve Aitken from March 25, 2005.
It's clear that I need to use two private addresses (from the example, these are 10.10.10.10 and 10.10.10.11). However, I'm not sure what are IP addresses 10.10.10.1 and 10.10.10.2 used for?
Existing BM servers have two NICs: first defined as private and the second as public addresses connected directly to Internet (they are from different subnets).

What do you mean "aren't able to get out through any of the ip
addresses"?
Do the addresses show up in any of the proxy nodes with display secondary
ipaddress? Does the proxy console option 17 show the server listening on
those addresses?
Is the gateway timeout error a BorderManager (or Windows) error? If
BMgr, then check that BMgr has a correct default gateway, DNS is working
(option 4 on proxy console screen) and try dropping filters for a test.

Got it working. I noticed that my dns setting in BM2 didn't coincide with settings in BM1. So, I made them the same and reinitialized the system on both servers. Of course, when I did that, it added the secondary IP addresses. So, I'm really not sure what was stopping it from working before, unless I have something misconfigured that's preventing the secondary addresses from loading. Go figure.

Error in creation of JCO with Load balancing server

Hi,
We are using a ABAP user base for our WEBAS server 6.40 (with ABAP+JAVA). i have created a Public group in concerned ECC 5.0 system. I have already configured SLD, and then i maintain data supplier bridge in SLD and run RZ70 in ECC 5.0 system to load system information.. i can see details in SLD ..
now i am trying to create JCO connections .. here i am unable to create JCO with load balancing option.. i get
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=<servername> GROUP=PUBLIC R3NAME=SID MSSERV=sapms<SID> PCS=1 ERROR service 'sapms<SID>' unknown TIME Fri Jun 16 12:41:20 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 MODULE ninti.c LINE 505 DETAIL NiPGetServByName2: service 'sapms<SID>' not found SYSTEM CALL getservbyname_r COUNTER 1
i am able to create single server JCO, but it fails in load balancing.. is there anything i have missed out in settings...
Thanks and regards,
Sudhir

Thanks, Bogdan Rokosa
I have the same problem,and solved it following the steps provided by Bogdan Rokosa :
you must insert an entry for your R3 system
(like: sapms<SID> 3600/tcp)
in services file
(C:\WINDOWS\system32\drivers\etc\services) on Java WAS.
I test the Jco successful without restart J2EE Engine.

Trouble in a SAP system with load balancing

Hello masters:
I had a trouble with workitems that came from a SAP system with load balancing. They doesn't receive the workitem ID in the UWL.
I created another system in the portal as a "dedicated application server", and made the necessary configuration in order to replace the first one, and then my workitems worked fine.
However, I would like to know what appened with the first system created as "system with load balancing". Why this system didn´t pass the workitem ID to the application (web dynpro abap) that execute the workitems?
Thank you.

I hope there was some missing configuration in the first case which was not replicating the workitem from SAP Inbox to UWL.
Thanks

Problem with load balancing on CSS

Hi, we have a pair of servers that are load balanced for port 80 traffic to 198.x.x.21 using the h_www_tcp:80 content rule . I recently got a request that port 80 traffic directed to 198.x.x.21/apps/auction be directed only to one of the load balanced servers. I created a service and content rule r_auction_tcp:80, but traffic still seems to matching the load balancing content rule and going to the wrong server (the /app/auction site only exits on the first server).
I thought it might be sticyness so I experimented by assigning my pc IP addresses that have not be used and I would still end up on the wrong server with some of the addresses.
Any ideals?
content h_www_tcp:80
vip address 198.x.x.21
port 80
protocol tcp
advanced-balance sticky-srcip
add service webwa1.1_tcp:80
add service webwa2.1_tcp:80
redundant-index 1064
sticky-inact-timeout 480
active
service webwa1.1_tcp:80
ip address 10.6.3.30
protocol tcp
port 80
keepalive type tcp
keepalive port 80
redundant-index 130
active
service webwa2.1_tcp:80
ip address 10.6.3.31
protocol tcp
port 80
keepalive type tcp
keepalive port 80
redundant-index 140
active
content r_auction_tcp:80
vip address 198.x.x.21
redundant-index 1077
add service webwa1.1-auction_tcp:80
port 80
protocol tcp
url "/apps/auction/*"
active
service webwa1.1-auction_tcp:80
ip address 10.6.3.30
protocol tcp
port 80
keepalive type tcp
keepalive port 80
redundant-index 131
active

does that never work, or is it just some requests that sometimes fail to be remapped to the appropriate server?
It should normally work, but with the current config it is possible to see failures for session that stayed idle.
The solution is then to increase the flow-timeout-multiplier under each content rule to 50.
