I am trying to connect to the cisco VPN server from my network which has linux firewall and windows 2000 systems. I have installed the Cisco VPN Client on one of the windows 2000 pro system and trying to connect and I am not able to connect with the error "Secure VPN Connection terminated localy by the client Reason 412: The remote peer is no longer responding"
When i went through some document in the net they say that
UDP port 500 UDP port 10000 (or any other port number being used for IPSec/UDP) IP protocol 50 (ESP) TCP port configured for IPSec/TCP NAT-T port 4500
Should be open
I am not soo good at IPtables. Can any one tell me how to open this ports in the iptables so that i can dial my vpn client
Plzz some one help me on this issue
