Hello. I am trying to set up a VPN connection between a Cisco VPN client and a Cisco 3640 using EZ VPN Server. I have a simple ACL on the inbound 3640 interface that reads:
permit udp any host x.x.x.x eq isakmp
permit esp any host x.x.x.x
permit udp any host x.x.x.x eq 4500
permit tcp any host x.x.x.x eq 10000
This is the only ACL on the 3640 interface.
When I configure the client to connect using Enable Transparent Tunneling -IPSec over UDP (NAT/PAT), I can connect the tunnel. When I select Enable Transparent Tunneling -IPSec over TCP - Port 10000, I cannot connect the tunnel.
Is the problem with the ACL or something else?
