Setting up as a NAT router

I want to try using Leopard Server on an Xserve as a NAT router. With 2 NICs the hardware is perfectly capable, but there seems to be a glitch in OSX that is preventing me from getting there.
I have Ethernet 2 (en1) set up for the LAN (10.0.0.0 network) and intend to use Ethernet 1 (en0) for the WAN side of things and to this end have the en0 configurations at the top of the list of ports (as per instructions). But...
NAT setup in Server Admin only lists ethernet ports that are open/connected. In order to do this I turn on the modem connected to Ethernet 1 and OSX configures the port from the DHCP server on the modem (192.168.x.x). Although this 'works' and allows me to browse the modem's web config GUI, it absolutely STOPS Server Admin. e.g. if I try and launch SA after switching on the modem, it sits there spinning the wheel without even showing a window - for as long as I wait. As soon as I turn OFF the modem (which de-configures the Ethernet 1 port) the SA window IMMEDIATELY appears and it commences its normal startup process. After which of course the only available interface in NAT setup is ... Ethernet 2:-(
Nothing else seems to suffer when the modem is ON and Ethernet 1 is configured and connected - just Server Admin and this leaves me with a bit of a problem.
When the modem is off, I cannot configure NAT in Server Admin as the required ethernet port is not listed, but when I turn the modem ON, I cannot run Server Admin.
Anyone any suggestions as to how I can prevent or get around this?

If you set up as a new phone, your iPhone will not retain its WiFi settings. However, these settings are stored in backups on iTunes, and are recoverable. If you restore from a backup instead of restoring as new, (provided that you have your iPhone backed up), then your iPhone will retain its WiFi settings.

Problem with WRT54G and DSL NAT router

I have a WRT54G connected to a Westell DSL NAT router. I would like to be able to allow incoming connections to my FreeBSD server.
The Westell router allows me to set IP Passthrough (they call it "Single Static IP"). This gives the WRT54G the outside IP address given to the DSL router. I can then set up the WRT54G for DDNS and port forwarding to forward specific ports I want to my server.
This works, for about 2-3 days. Then, I start to randomly lose outside connectivity. Web pages start coming up with missing elements, or taking a long time to load. This will eventually lead to total loss of outgoing communication.
Normally, I would blame this on the Westell NAT router, but as I'm losing connectivity to the internet, I'm also losing connectivity to the WRT54G. It will try to load configuration pages but will be slow with missing elements, etc.
All communications between computers on my inside network continue to function properly, it's just connectivity to the WRT54G and the internet that seem to start to fail.
Does anyone have any idea what is going on? I just upgraded the firmware on the WRT54G from 1.01.1 to 1.02.0, but I don't imagine this will help.
Thanks,
David Chamberlain

Try setting the MTU to manual and change the value to 1450

But remote assistance ( msra.exe ) use a dynamique port and never the same.
How to use a fixed port for remote assistance ini windows 8.1 ?
And why i can't use easy connect ?
i read that the router must implement the PNRP protocol. I think it's a propriatary microsoft's protocol unknow on my router.
Thanks

How set up macbook pro Internet router?

how set up macbook pro Internet router?

But isn't the MacBook Pro connected to the modem and being used as the router? You can only share an Ethernet connection wirelessly. You only check the box to share the Ethernet connection to Wi-Fi. Do not check any of the other boxes. You select Ethernet from the dropdown menu as the connection you will share. Your preferences should look like this:
The only difference will be that yours will show just Ethernet, not Ethernet 1.

It's Internet Sharing you're looking for in System Preferences>Sharing, which can share your connection, say from Ethernet to other computers/devices using Airport/Wifi.

RV180 - DDNS behind 2nd NAT router

Hello community,
is it possible to use the DDNS feature (dyndns.com) behind a 2nd NAT router?
Network is as follows:
INTERNET - NAT-Router (unknown device) - Cisco RV-180 (NAT) - Clients
Kind Regard,
Michael

If you put your dyndns client in front of the rv180 or one the nat router's dmz, you should get the correct IP address. I usually use the DMZ port on a nat router when putting a vpn router behind a nat one--this solves a lot of the IP address issues for the vpn router.

WRT54G....Can I set DHCP to use the router for DNS instead of external DNS?

Hi folks. I cant' get my router to have DHCP tell my PCs that the router should be the DNS server instead of the external servers it is using. I am using Comcast Cable internet. It sets the external DNS servers for every PC that connects to it and I have problems finding my PCs on my network by NetBIOS name because the external DNS servers obviously don't store my local PCs. How can I set the router up to set DHCP to use the router for DNS?

If you cannot set the DNS server in the configuration page for the DHCP server in your router then your router does not support this.
This won't solve your problem though. The DNS server on the router is a simply forwarder. It simply forwards the DNS requests from your computer to the ISP's DNS servers. The DNS server does not accept dynamic updates to a private zone inside your LAN. And DNS is pretty much unrelated to the standard windows workgroup browsing which does the actual name resolution inside your LAN. That name resolution even works without a router inside your network. Basically all windows computers in your network periodically broadcast their name to the network. One windows computers is elected "master browser" which collects all these names and provides the name resolution service for all computers in the workgroup.
If this does not work it is most likely a windows configuration problem. It could be a software firewall on the computers which blocks traffic. It could be that the computers are not setup for file/printer sharing and thus have the computer browser disabled. It could be that your computers have a WINS server configured which does not exist. There are probably more causes. The better source to ask this question would probably a Microsoft support group. They deal with these kinds of issues more often and maybe a MVP may be able to point you into the right direction or give some links to step-by-step instructions...

WLSE manage AP using SNMP through xDSL line with an NAT router

Hi,
This is the deployment architecture that I had :
WLSE (Internet public add)--->xDSL----->NAT router---->BBSM--->APs
I had a problem in managing the APs which the ip address will be translated to a public ip addresses. When I use discovery options from my WLSE, it does not find any AP. I enable the CDP on my router and APs. There is only 1 ssid on all my APs.
Is it possible to manage the APs using snmp using this model?
regards,
Sam

Since you have NAT in between the WLSE and the APs, this will not work. SNMP does not work over NAT. To test this, try using the SNMP Reachable Tool under Administration->Connectivity Tools. enter the ip address and click on SNMP Reachable, you'll see that it will time out.

Does Stratus/RTMFP support P2P behind the same NAT/Router?

Does Stratus/RTMFP support peers behind the same NAT/Router?
(such that both peers have the same public IP address)
That is: if two computers (each running Flash) are behind the same NAT, and connect to Stratus to get peerID;
do we expect they can connect p2p?
Or will each one get/see just the public IP address:port of the other?
My initial tests indicate that this scenario fails [ICMP Destination Unreachable (port unreachable)]
Is this just a limitation of my local router? does this work for others?
Does Status expect the local router to detect/decode/resolve this situation?
If the solution requires 10.1 groups, is there support to detect/diagnose when/if the peer is on the same LAN?

Thanks for the info, sounds like RTMFP supports this, and hopefully the AFP code does the right thing.
[so, officially, the original question is answered]
Note: In one instance, i'm running two browsers on the same host,
so even the inner/LAN addresses would be the same. Therefore, if A sends to B's inner/LAN address,
the [Windows] OS network layer *should* recognize that and 'hairpin' without leaving the host, or crossing the firewall.
(I say "should" because Unix generally does that, but I'll have to check to see about Windoze).
[And such packets are probably invisible to Wireshark also, so how do i verify what's happening?
oh sure, just reconfigure to boot Linux... ]
So glad you explained that the client tries all three pathways; if it works as you say,
then I can probably ignore the ICMP error from the local router (or, as you say, teach it to do the hairpin).
Can you confirm that P2P will work between browsers (say Chrome to Firefox) on a single Windows host?
[I really want to know if I'm failing because of network configuration or application code/error;
at this point, I am able to correctly exchange the peerIds, and start the NetSteam.play,
but the two sides do not appear to be exchanging audio/video]

Airport Express (802.11n) as non-NAT router?

I am considering to replace an old WLAN router by an Airport Extreme. For this, the Airport Extreme unit would need to work as a non-NAT router (my network consists of multiple independent subnets). I've looked through the (very helpful) discussions, but could not find a definitive answer to this question. So, can you tell me point-blank whether an Airport Express (802.11n) base station can be used as a *non-NAT router* (connected to subnet A via the WAN port, creating a different subnet B on the LAN ports)?

broadwater, Welcome to the discussion area!
No this can't be done. The AirPort Extreme base station (AEBS) can be configured to create a single subnet for all clients (LAN port or wireless) but in that mode DHCP and NAT are enabled.

How to set up DNS behind a NAT router...

I am trying to configure DNS in Panther Server as the SOA for my domains and as a LAN name server. I've read several explainations about setting up DNS including technical document 106853 "How to set up DNS in a NAT environment" which says:
Note: For Mac OS X Server 10.3 or later, you should use the Server Admin
application to configure DNS and NAT. Please see the Network Services
Administration Guide for additional information.
Seeing how picky BIND is, this sounds like a good idea, except I can't configure views like that.
Questions:
1) What happens if I create an A record in my main domain for newmac.mydomain.com-->10.0.1.2? People outside the LAN can't get to it, right?
2) Can I create really simple names for the LAN like newmac-->10.0.1.2?
Thanks!

You can use "system-config-network" command to configure your DNS configuration.

Internal DNS server and NAT routing issue.

Hi -- I am not terribly experienced with DNS and I am running into an issue that I can't seem to resolve. My company.com DNS information is hosted by an outside ISP for email, web, etc... but I have configured an A record there to point to the public IP to my mac os x server (server.company.com).
We have a cisco router configured with one to one NAT from the public IP to the internal IP for our server in a 192.168.15.x subnet. The same router is running DHCP and and NAT on that subnet under a different public IP provided by our ISP.
Our server is running DNS with recursion and has a "company.private" zone set up for internal services and machine names. Thus, the server is accessible via "server.company.com" from the outside and "server.company.private" from the private LAN.
The problem is that I would like to be able to access some services simply via "server.company.com" both inside and outside the private network. Now, accessing the "server.company.com" services from the private lan does not work because the name resolves to the external IP and the external IP cannot be used internally due to NAT.
Is there a way to configure my internal DNS server to respond with the appropriate private address when receiving a query only to "server.company.com" and forward requests on for anything else on "company.com"?
I know that I could manually duplicate all entries for our domain from my ISP and host the same entries for internal clients, but it would be much easier to only have our server handle requests for itself. The server is running OS X Server 10.4.11.
Thanks

Is there a way to configure my internal DNS server to respond with the appropriate private address when receiving a query only to "server.company.com" and forward requests on for anything else on "company.com"?
Ordinarily, no. Once your server thinks it is responsible for a zone (e.g. company.com) then it will answer all queries for that domain and never pass them upstream. Therefore you'd have to replicate all the zone data, including all the public records, and maintain them both.
The one possible exception to this (I haven't tried) is to create a zone for server.company.com that has your internal address. In theory (like I said, I haven't tried this), the server should respond to 'server.company.com' lookups with its own zone data and defer all other lookups (including other company.com names since they're not in a zone it controls). Might be worth trying.
