I'm trying to set up Ipsec VPN to a remote Windows server. I opened ports 1701 (TCP) and 500 (UDP) on the Cisco router. However, when I netstat from the LAN, the server isn't listening on these 2 ports.
I've checked all the firewall settings to see whether the issue is, and it seems to be configured well. Could it be the Cisco router port forwarding settings I configured? (see below)
