VPN client cannot connect to inside network

[splicerguy]

Hi,

My clients are able to connect to my PIX using the Cisco VPN client, however they cannot connect to any internal computer.

I've tried a bunch of different changes to my config (based on other people's similar problem), but I've probably just muddle it up more.

Here's my config. I'm a bit of a newbie, but assume it has to do with NAT?

In addition to the code posted by unclerico you might want to create proper subnets for your vpn pool, makes ip management easy. See if the code below works.

I've made those changes yet I still cannot connect to computers on my inside network (172.16.x.x)

When I do an IPCONFIG on my client pc, this is what it shows:

Bizounett,

Try this

access-list inside-out permit tcp host x.x.x.x any eq smtp

Where inside-out is your outbound traffic acl and x.x.x.x is your internal smtp server ip.

Hello Splicerguy,

Try this -

route inside 172.16.0.0 255.255.254.0 172.16.1.253

-Viconsul

 

[unclerico]

Try adding this in:

no access-list nonat line 1 permit ip host 192.168.0.33 host 192.168.0.62
access-list nonat permit ip 172.16.0.0 255.255.254.0 192.168.0.32 255.255.255.224

nat (inside) 0 access-list nonat

[splicerguy]

I tried both suggestions but still no joy

 

[unclerico]

Is the PIX your main gateway on your internal network or do you have something else in the mix like a separate layer 3 switch?? When you get connected to the VPN can you issue a route print and list the results??

The PIX is my main gateway on the internal network. Nothing else in the way.

Try adding this to your windows client:

Thanks, that worked. I've fix the config so now the correct route is always added.

Thanks again
