PIX 501, Disable Split Tunneling

dacruzer1 — Mon, 11 Mar 2019 18:41:57 GMT

Hi Everyone,

I have a PIX 501 on a remote location and connected via a VPN tunnel to a PIX 525. How do i disable split tunneling on the 501 so that internet access will got through the 525. (We have a requirement that all of our PCs need to go through our filtering device). Below is the config of the 501:

Thanks

Alfred

Since you're using the same ACL for NAT and VPN (I assume you have a single tunnel)...

Then you include in that ACL lvccld

the traffic to any:

i.e

access-list lvccld permit ip SOURCE_IP SOURCE_MASK any

Make sure on the other end (PIX 525) you have the inverse ACL also.

Other things might be needed in the PIX525 to allow internet access for this traffic.

Federico.
