I am trying to get a vpn connection to get pass the PIX firewall and have access to a network. So far I haven't been very successful.

Here are my configs:

PIX 515:

access-list acl_out permit tcp any any eq telnet

access-list acl_out permit udp any any eq 23

access-list acl_prinetwork permit icmp any any

access-list acl_prinetwork permit tcp any any eq telnet

access-list acl_prinetwork permit udp any any eq 23

access-list 1 permit ip 172.16.4.64 255.255.255.192 172.16.5.0 255.255.255.192
