Re: Cisco AnyConnect Remote Access to L2L tunnels

["Todd Simons" <tsimons () delphi-tech com>]

I got it running (hairpin +NAT solved it), but I don't have external traffic (it's a global tunnel).   For example 
Internal hosts to www.google.com works, but it doesn't work from a RA VPN.  The RA VPN's use an IP Pool of addresses in 
my LAN subnet

In my logs I see the "Built inbound TCP" connection, but I never get a response.

Here's my NAT statements:
global (outside) 1 interface
nat (inside) 0 access-list insideNoNat
nat (inside) 1 0.0.0.0 0.0.0.0

the insideNoNat contains our known addresses, no references to public subnets.

Hey Todd--

   I have not tried this before with AnyConnect VPNs, however, at one
time, I think I had a similar set up with remote access IPsec VPNs and
L2L tunnels.

   OK, you have the hairpin enabled and you the SSLClientPool IP block
is included in the ACL that marks interesting traffic. Good.

   Have you watched the logs when an AnyConnect client is trying to
access one of the remote L2L VPN locations? I am thinking right now
that the "crypto map OutsideVPN 192 set nat-t-disable" may be the
issue. Can you try enabling NAT-T
