I have a Cisco 2811 Router with 3 ADSL WAN Wic’s.

I have a number of remote sites that I want to setup via a site to site VPN link. Setting this up via the first WIC or other WIC is no problem however when I setup a number of sites to use the first WIC and proceed to setup additional sites using the second or third WIC I keep getting phase one errors.

As soon as I reconfigure my remote router with the peer address of the first WIC on the 2811 it connects without any problems.

Any suggestions please.

Peter,


Might be a bug?

You should not have any problem regarding the amount of VPN tunnels configured (as long as it is supported by the router).


For example,

For the router should be exactly the same having a single tunnel terminating or 10 tunnels on either WIC.

Which IOS are you running.

Hi Federico


Thanks for the response, see below router IOS versions.

I agree it should not make any difference, I just can't figure out why I should get phase one errors just because I am setting up aditional VPN's on the second WIC or Third WIC
