Hi all
I have an ASA5505 in NEM mode, connected to a 2621xm Easy VPN headend. I can get the NEM tunnel up, and there is full internal connectivity within the internal network (site A uses 10.1.0.0/16 and site B uses 10.2.0.0/16).
However, I can't seem to get split tunneling to work at site B where the ASA is, in spite of having the following config on the headend. Does anyone have any suggestions?
crypto isakmp client configuration group EasyVPN_NEM
key vpnkey
acl Split-Tunnel
ip access-list extended Split-Tunnel
permit ip 10.1.0.0 0.0.255.255 any
Thanks!

Hello,
If the communication works fine over the VPN tunnel, you should check if you have NAT properly configured on the ASA side to reach de Internet.
Can u please post the ASA's config?

Thanks for looking into this Dennis. Here is my ASA config. It was built by ASDM as I'm not familiar with configuring ASAs.

Well, the configuration looks fine to me...just to clarify...your problem is that you cannot reach the internet from the network behind the ASA? right?

That's right. I can reach the HQ site internal network just fine, though.
