Hi Jian,
The 2 basic changes you need to make on this device is to add the route and
you can add to your nat 0 (mpls) for the network that needs to be reached to
the vpn client pool. Something like this:
Access-list vpn_outbound_nat0_acl permit ip 192.168.20.0 255.255.255.0
10.10.37.0 255.255.255.0
Obviously you need to remove the existing route as you said.
If you need more help please provide the other configs!
Tony

I have the configuration attached, this is working configuration (before cut
over) RA VPN traffic comes in from outside interface and route to site2site
interface, the only change to make traffic cutover to mpls interface is
replace "route site2site 192.168.20.0/24" with "route mpls 192.168.20.0/24"

This isn't a hairpin issue if I read this correct (different security
interfaces). If he was using hairpining previously he's on >7.2 as that is
when the command was introduced.
If you'd be kind to send all the configs with sensitive info removed we can
help you out.
