I configured two 876 routers for DSL and ISDN backup connections between two sites.
I first configured ISDN and checked the connectivity and everything worked.
I then congigured VPN (IPSec tunnel) and also the firewall and i get the following weird response from the router.
The VPN works fine but when i disconnect/ disable the WAN port the ISDN gets up but traffic doesnt flow from one site to another. I can ping the other ISDN peer (only from the ISDN interface)but packets dont pass through from the ethernet interface.
The VPN is configured through SDM tool and I have configured the DSL peers and traffic to be encrypted / decrypted at the ethernet (VLAN) interfaces. (I also tried to setup a VPN with encryption /decryption at the DSL interfaces but it didnt work...)
PS. Since the other router is at a customer site is there any way I can reboot the router remotely so that i can experiment with the router and if something goes wrong to get back to the working state without losing the configuration??
