I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This comes down to NAT rules most likely. Most nat exemptions include where all the remote access clients can go such as subnets at the main sites and other remote sites, but rarely do they include (or need) to allow RA clients to communicate directly with other RA clients. There is an increasing need when it comes to remote telephony users.

Anyway, you need to add in a nat exemption to allow traffic to/from the RAVPN subnet, and also make sure that the subnet is included in the split tunnel if a split tunnel is used.

example:
RA Clients receive IP's in the range of 192.168.255.x/24

object net SUBNET-192.168.255.0-24
subnet 192.168.255.0 255.255.255.0

!add the RAVPN subnet to the existing split tunnel ACL
access-list splittunnel standard permit 192.168.255.0 255.255.255.0

nat (any,any) source static SUBNET-192.168.255.0-24 SUBNET-192.168.255.0-24 destination static SUBNET-192.168.255.0-24 SUBNET-192.168.255.0-24 no-proxy-arp



All things depending on your rules, using (any,any) might be great or it may cause problems. If it causes problems, just be more specific and use (outside,outside) or whatever the name of the internet that VPN users connect to is called.
