Question regarding a Cisco 837 ADSL Broadband Router

Unanswered Question

We have a hub and spoke vpn setup with all Linksys 10/100 16-Port VPN Router RV016. There are routers in front of all branches configured as bridges and all tunnels are working fine except the one that has the Cisco 837 ADSL router in front. Is there anything we can do on the 837 to resolve this? An access-list perhaps? Thanks in advance.

you mentioned all other routers are running in bridging-mode. i was wondering whether the 837 is configured in bridging-mode as well.


below is the sample config for 837 running in bridging-mode:

one point needs to be noticed is that after applying these code, remote access such as telnet or ssh will not be able to establish to the router. console is the only option.
