Makes sense I guess. Only problem is I only have one Ethernet port on the Adtran. If I change it to bridged mode, do I then lose my ability to administer it from the Ethernet side? Will all traffic automatically go to the Cisco? I'm assuming this is done through telnet. Any previous commands I need? Any subsequent commands? I mean, anything I need to do to get the router into a mode where it's expectingthese commands? Anything to do after I do these commands? I'm assuming, since this will bypass everything, if it doesn't work, all I have to do is type "bridge-group no"? I don't have the docs for this router. Thanks again. - Keith

So, I'm trying to set up a VPN tunnel between two sites. Site A has a RVS4000 as the router to the internet. Site B has a Adtran NetVanta 3200 to convert a frame relay to ethernet, so I can't replace the Adtran. How do I set this up so I can create a tunnel between the two Cisco routers? I have static Internet IP addresses for the Cisco at Site A, the Adtran and Cisco at site B. I have configured the two Ciscos to set up their tunnel and I've been able to establish the tunnel between my house (where I put Cisco B in place of my home router as a test) and the Cisco at Site A. So, I know my tunnel settings are ok (with the exception of IP address changes). I'm being told by some people with more network experience than I have that there are a few options. 1.) put the Adtran in bridge mode and use the Cisco as the firewall, DHCP, etc. No clue how to do that. 2.) put the Cisco in a DMZ set up on the Adtran. If I do that, it wouldn't really give me access through the VPN to the network, right? 3.) set up static routes between the Adtran and the Cisco? static using the internal IPs or the external ones? Very confused. Here are some of the IPs for Site B. I'm not concerned about Site A since I know the internet works there and the VPN tunnel settings are easy enough to change once I actually get the internet working with the two router combo at site B. Adtran - internal IP - 192.168.1.1 mask 255.255.255.0 - external IP - X.X.24.179 mask 255.255.255.248 (mask may be wrong - based on memory) Cisco - internal IP - 192.168.3.1 mask 255.255.255.0 - external IP - X.X.24.176 mask 255.255.255.248 (again, mask may be wrong) I don't care which one does the firewall, NAT, etc. To me it would seem easier to have the Adtran send all traffic to the Cisco, then let the Cisco do the rest (VPN, firewall, DHCP, DNS, etc.). I'm open to all options - as long as it works. Thanks in advance for any replies.
