Ok, I need some help please with a problem with a Site to Site VPN.
Ok, well we have a ASA5520 using asa825-k8.bin that connects to another company site to site vpn tunnel it is working fine no issue, until the other company is changing the connection from there current firewall to a new firewall with a new IOS and different public IP address.
The problem when we try to get the new tunnel up with the new public ip address with the new PSK, but we are using the same internal ip address and Group Policy no traffic will pass not pinging or traceroute from here side.
The other company makes a few routing changes on there side but nothing works.
What commands could i used to find out the issue is either on my side or the another company side?
