PIX 501: VPN user can't access the private network

[colema19]

Hello everyone, I'm trying to get my VPN user(that is, me) to be able to access my home network when I connect. Right now I can't ping or otherwise reach any machines in the private network.

I'm only using PPTP, and I've got that working(I can connect, I get an IP in the space I expect).

I add a route entry to the client machine when I dial in, but I can't seem to get a response from any of the hosts in the local network. I suspect I'm missing something in the acl, but I'm sure what.

More specifically:
Dialup is assigned 192.168.100.x address. Can't seem to access any of the machines on the 192.168.0.x network.

The route entry I add to the client is typically:
route add 192.168.0.0 mask 255.255.255.0 192.168.100.1

Thanks!

This is my config:

change this:

access-list inside_outbound_nat0_acl permit ip any 192.168.0.0 255.255.255.0

to this:

access-list inside_outbound_nat0_acl permit ip 192.168.0.0 255.255.255.0 192.168.100.0 255.255.255.192

I noticed your local pool was only using .1 - .50 so you see the subnet mask in the nat0_acl as .192 accounting for 62 hosts. You can change it to a full /24 if you need.

Ah thanks, that got it. So I needed to specify an access rule to let traffic flow back to the dial up user? But I don't need one to specify traffic can go in? Either that or my idea of what the sip and dip are backwards from what the pix treats them as.

 

[unclerico]

that's right. the return traffic from the inside was being NATed. when you added the sysopt connection permit-pptp to your config you bypassed the need for any ACL's for traffic destined inbound from the PPTP group.
