I have users from my HQ who can only connect to their e-mail via Cisco VPN client. Unfortunately they are unable to that from within my network. Which ports must be opened for Cisco vpn clients to work from within my network

The Cisco VPN server that these VPN clients connect to must be configured to use NAT-Traversal.  You should only need to allow UDP 500 and UDP 4500 outbound as long as NAT-Traversal (NAT-T) is enabled.
