VPN Client stops communicating frequently
Posted on 2014-01-27
I have an Cisco ASA 5540 Firewall and its configured with Remote Access VPN. Remote client uses Cisco VPN client
I am facing an weird issue.
One of the client have an access to specific server and I have lock down with ACL to access only this server.
The VPN client suddenly stops communicating with server. I cannot ping.
After my troubleshooting I have discovered, when the VPN client receives the same IP address from ASA such as 192.168.1.1..it will not work
When I changed to 192.168.1.2..it will for sometime then stops. Again I need to change the IP to 192.168.1.3 and so.
Having said that, I can ping to other servers ( by changing the ACL) but cannot ping to this server.
The server Oracle Linux
I would highly appreciate any help.
