Go ahead and give us a
static (inside,mpls) 10.10.10.0 10.10.10.0 255.255.255.0 (in SJ)
or
static (outside,mpls) 10.10.10.0 10.10.10.0 255.255.255.0 (in SJ)
You can troubleshoot these quickly with debugging logging. You'll see the
failure of connections in the logs...

Subject: RA VPN users can not ping remote LAN
Hi, all,
This is a real world scenario, we have two offices one in San Jose and the
other one in LA, the network is very simple, each office has a PIX 515 and
has one L3 subnet directly attached to firewall's inside interface, the
subnets are 192.168.1.0/24 and 192.168.2.0/24, respectively. Each firewall
has two public IP addresses, one public address dedicated to Internet access
and IPsec RA access, and the other public IP is dedicated for site2site VPN,
the address pool for remote access VPN in SJ office is 10.10.10.0/24, while
remote access pool in LA office is taken from 192.168.2.0/24 space. So
everything worked fine, when employees VPN in to either firewall, they can
access Email/files in either location.
We now decided to get rid of the site2site VPN and go with MPLS VPN service
provided by ATT, the MPLS VPN service was attached to third interface
(nameif MPLS) in firewall, we changed the static route on firewall such that
traffic between two offices are routed to interface MPLS, the cutover is
successful, means that hosts in both offices can communicate with each other
fine.
The only problem is remote access users can only access servers in their
local office but can not access servers (or ping) in remote office, I think
somehow firewall does not route traffic coming from RA VPN to the new (MPLS)
interface, but I can not figure out why is so, because the routing looks
correct, and NAT translation also OK.
If you guys have any suggestions, please guide, I can post the relevant
configuration if that helps.
Thanks,
Jian
