Hello.
Our company connecting to internet throught Linux server with NAT.
On linux server installed Cisco VPN client and users in our locale network working with remote network over this VPN connection.
But somebody users have Cisco VPN Client's (they heave accounts to other remote networks)on their workplaces.
And until VPN connection on Linux-server is on, their other VPN connections don't working. VPN client establish the vpn connection and can send packets to remote network, but don't recieve packets from remote networks.
If connection on Linux-router is off - all working good.
Why?
