Cisco VPN client through a PIX Firewall

CSCO10576352

Hi, has anyone ever configured a pix to site between a local LAN switch and an internet broadband router to basically block all trafic except for outgoing vpn connections using cisco vpn client to a cisco vpn concentrator from pc's located on the local LAN.

If anyone has got this kind of setup working then it would be usefull to get an overview of how, I have searched the net but can't seem to find anything specific to what im trying to achieve.

The info im interested in is what specific protocols/ports need to be allowed through, any speatures that need to be enabled on the pix, etc.

Thanks in advance.

The ipsec vpn ports which would need to be allowed through would be

udp 500

udp 4500

protocol 50 esp

You could simply create an access-list on your inside interface allowing only these ports outbound.

access-list inside permit udp any any eq 500

access-list inside permit udp any any eq 4500

access-list inside permit esp any any

access-group inside in interface inside

or more specifically

access-list inside permit udp any host eq 500

access-list inside permit udp any host eq 4500

access-list inside permit esp any host

access-group inside in interface inside

Thanks for the prompt reply, ill try that out.
