I referred to config I downloaded to setup my pix. I have a question about some of the commands. For instance what does vpngroup groupmarketing "split-tunnel 102"- Now I know what the group command is referring to but I don't know what split-tunnel 102 means. Also what is a "crypto map"?
The 'split-tunnel 102' command enables the split tunneling with access-list number 102.
The access-list 102 defines which traffic flows through the tunnel, others will be sent to gateway for normal internet access.
The 'crypto-map' command is used to define/bind remote-peer IP, transform set, interesting access-list, which need to be applied on outbound interface, normally on the PIX outside interface, where the outbound VPN traffic is sent out to remote peer.
1. Define interesting traffic (to go through vpn tunnel) using access list. This access list only allows traffic from network 192.168.12.0 to reach 10.0.0.0 via vpn.
access-list 102 permit ip 192.168.12.0 255.255.255.0 10.0.0.0 255.0.0.0
