Pix 501 Split Tunnel - How To?

Hello,

I have a customer who wants to give their employees the ability to surf the web while they have a secure tunnel to the office from their home computers and laptops.

I have configured the Pix per instructions I found on the web, but can't seem to make it work. I can access the data on the fileserver with no problem from outside the workplace via VPN Client 5.0. However, I have no success surfing the web while connected with the VPN Client. I have checked "allow local LAN access" on the transport tab of the properties page.

Below is my Pix configuration. I would apreciate some input on how to accomodate my client.

Thanks in advance,

Buck

change access-list split to: access-list split standard permit 192.168.1.0 255.255.255.0

Ummm, not in PIX 6.3(5): it doesn't have access-list standard. And PIX 7 and PIX 8 use access-list standard only for OSPF routines.

However, it would be a good idea to change the entry to

access-list split permit ip 192.168.1.0 255.255.255.0 192.168.9.0 255.255.255.240

Excellent catch Walter! Been dealing strictly with ASA's lately and they are supported on that platform.

Brian,

Thanks for the input.

I also have a few customers who have ASA units. Your input will be helpful for when/if I need to enable split tunneling in them.

Thanks!

Buck

Walter,

Can we do the same in FWSM ? vpn users connect to vpn concentrator3000 authenticated over ACS and access servers allowing access on FWSM. we have same problem that when a user connect vpn they are unable to use browse internet.

Your valueable input required.

Regards, AB
