Level 1

Hi all,
i have a main site with a 192.168.3.X address  (Cisco router 897VA).
I have a branch office with 192.168.4.X address (Cisco router C870).

 

Site to site vpn work perfecty between two sites.

 

In main site i have vpn anyconnect configured,and it work fine.

 

The problem is when i connect to main site(192.168.3.X) through anyconnect i can't reach remote site(192.168.4.X)

 

My config :

Someone could help me to resolve this problem ?

 

Thank you in advance.

Hi,
You will need to modify the ACL used to define the interesting traffic between the main and branch sites to include the AnyConnect VPN IP address pool network?

Also you will need to check that you do not have a NAT rule inadvertently natting the anyconnect traffic to the branch site.

If you still need further assistance, post your configuration for review and the output of "show crypto ipsec sa"

HTH

I added my config
