ASA 5505 stops local internet when connected to VPN
- by g18c
Hi I have a Cisco ASA router running firmware 8.2(5) which hosts an internal LAN on 192.168.30.0/24.
I have used the VPN Wizard to setup L2TP access and I can connect in fine from a Windows box and can ping hosts behind the VPN router.
However, when connected to the VPN I can no longer ping out to my internet or browse web pages. I would like to be able to access the VPN, and also browse the internet at the same time - I understand this is called split tunneling (have ticked the setting in the wizard but to no effect) and if so how do I do this?
Alternatively, if split tunneling is a pain to setup, then making the connected VPN client have internet access from the ASA WAN IP would be OK.
Thanks,
Chris
