PIX VPN Client Issue

[GregNVMC]

Hi Guys,

I've setup a VPN on a PIX 501 running version 6.3(5) to accept connections from the Ciso VPN client (I'm trying this with v4.8.01.0300 of the VPN client).

I can get connected just fine, but once I'm connected the only thing I seem to be able to do is ping the inside interface of the PIX and the IP that the VPN client gets assigned. I cannot access any of the subnets that are behind the PIX.

Here's my PIX running config:

----------------------------------------------

I'm specifically trying to access a host that hangs off a switch further in the network behind the PIX. In order to reach this host, there is an L3 Cisco 3550 switch that is directly connected to the inside interface of the PIX and that switch is connected to the switch that has the host hanging off of it.

The IP of the host I'm trying to connect to is: 172.31.3.100
and the L3 switch IP is 10.250.10.2

I can't ping either of these things when I'm connected via the VPN client. However, both of these devices ping just fine from the PIX when I'm consoled in to the PIX. In fact, all inside devices ping each other fine. It just doesn't work when I'm connected over the VPN client.

I'm happy to post the switch configs if required, but I thought I wouldn't do that straight off since this is already a long post ;-)

Any help or suggestions where I'm going wrong are greatly appreciated.

Thanks and kind regards,

Greg.

add:

access-list nonat permit ip 10.250.10.0 255.255.255.0 192.168.253.0 255.255.255.0
nat (inside) 0 access-list nonat

then try

Awesome!

That worked like a charm. Thank-you sooo much, your help is very much appreciated ;-)

Kindest regards,

Greg.
