IPSec ov UDP: what ports to open, please

I'm trying to run the Cisco VPN client v4.8 through a Cisco 831 router. Can anyone tell me what ports should be open?

Re: IPSec ov UDP: what ports to open, please

If you are initiating vpn client connectivity from behind the 831 to outside you need to allow through the IPsec ports udp 500, udp 4500 and protocol 50 esp.

e.g

access-list 101 permit udp any any eq 500 log

access-list 101 permit udp any any eq 4500 log

access-list 101 permit esp any any log

apply acl-101 to your outbound interface

ip access-group 101 in
