So basically, you either have to drop the VPN clients that connect
into a subnet that is already able to get across the tunnel, or add a
new subnet and setup the "interesting traffic" ACL to have your new
subnet in it on both sides of the tunnel.

Also if you add a new subnet, you'd have to add that new tunnel to
your split tunnel list, if you're doing that.

Please feel free to ask if you have questions about all this.... I'm
doing what you describe right now on my ASA at work, and it works like
a champ... at least that lets you know it is entirely possible

Hello Todd

Please check out this link from Cisco, it details a very similar
configuration:

http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a008046f307.shtml

Please let me know if you need any further help.

Regards

Farrukh

I am pretty sure one of the two session discussed that.

Hey Todd--

A couple questions:
1) Is the ASA a peer for the L2L tunnels?
2) Are crypto maps for the L2L tunnels on the same interface as the
AnyConnect VPN?
3) Do you have the hairpin enabled?
4) Can you send a copy of the ASA configuration?

A couple questions:
1) Is the ASA a peer for the L2L tunnels?
>>Yes

2) Are crypto maps for the L2L tunnels on the same interface as the AnyConnect VPN?
>>Yes

3) Do you have the hairpin enabled?
>>I think so (lines 48/49 in attached txt)

4) Can you send a copy of the ASA configuration?
>>Attached. Note that this is not a production ASA, config is still a work in progress. This should be considered "MainSite" and SiteA, SiteB, SiteC are satellites, RA VPNs terminate here at MainSite and should give access to SiteA, Site and (eventually) SiteC. SiteA has 2 IPSEC Networks, the remote gateway & a /29, SiteB just has the remote gateway, Site C will just be a /27. The tunnels that use the remote gateway are actually used for ingress traffic from Sites.

Thanks
