Hi all,
I am having plenty of trouble trying to get my network connecting to the internet via a 2621XM router.
I currently have my network connecting to the internet through an ISA Firewall/Proxy but am wanting to replace this with the 2621XM.
The router has been configured correctly (I assume) from what I have read on the net as wel as from a few colleagues who know more about the ins and outs or this stuff. Access to the internet is still not happening.
I have configured FA0/0 as the outside interface and FA0/1 as the interface. The config for my router is attached. (See file 2621XM_Config - Original.txt)
Once thing that my friends told me was to configure the outside interface with the static IP supplied to me by my ISP.
I know I would only do this if I had my modem in Bridged mode, but as it is currently NAT'ing from my static IP to a 10.x.x.x address, i need not bother with altering it. Should I change it?
(See file 2621XM_Config - Modified.txt)
My internet service is via ADSL.
Neither method has not worked, so I am thinking that there is something missing in each of the configs.
Two questions need answering that I am unsure how to proceed with:
1. the ip domain-name... should this be my public domain name or my internal domain name?
2. the ip name-servers... should these be my ISP name servers or my internal name servers?
My ISA proxy/firewall is setup as a forwarding-only name server and uses my ISP name-servers to forward any requests my internals are unable to resolve. The 2621XM will effectively be doing this from now on.
Does anyone have a working config of a 2621XM that I would be able to use or work from to get my setup working correctly?
Thanking anyone in advance who an help me resolve this.
regards,
Darren

Hello Darren,
being a NAT command you can only convert your internal DNS server to the ip address of the WAN interface of your router.
So read global-address = router wan ip address.
Hope to help

BTW,
strangely enough when I do a sh ip route, I am showing an address associated from my ISP: 203.17.101.65
This, according to an nslookup on that address is a loopback address.
I guess something is getting out to come back in, but when attempting to ping any other address from the router, i get no response, even the 203.17.101.65 address.
regards.
** amendment **
When I pin thi address from the router, i get a response. From the command prompt window, I get nothing. NSlookup provides the details of the address.
