VPN site to site, can ping WAN IP, but cannot reach internal

trinhphanle

Level 1

Hi all

I need your help. I have 02 router cisco 892 for VPN site to site. I reconfigured the second one and they can ping public IP together.

However they cannot ping other site's internal IP address. The second one does not have certificate like the first one. I am not sure

that is the problem, because both use pre-share key. I think they do not need certificate method for VPN, am I right?

And what is the problem when I cannot reach internal network?

Thanks for your help

I don't see an IP address for the LAN on "2nd site"

Sorry m.kafka

The IP address in the 2nd site is:

Fast Ether 8: 192.168.x.x 255.x.x.x

Do I need route for those 02 router? Because they are VPN router, I think not need, but you can correct me.

Thanks for your help.
