Inside Static Route

We have two sites: 192.168.100.x and 192.168.101.x currently connected  via IPsec VPN. On each end we have a Cisco ASA 5505. However, each site  also has an MPLS VPN with intentions to move all traffic to this link.

Site A: ASA inside interface is

Site B: ASA inside interface is

The  ASA at site B is failing (keeps power cycling itself) so we want to  move all traffic over to use the MPLS link as obviously the MPLS as  better QoS control. The MPLS VPN is connected together via two Cisco  2800 routers.

Site A: Telco MPLS VPN (CPE) inside inter.

Site B: Telco MPLS VPN (CPE) inside inter:

We want to keep the ASA @ site -  this site has remote access needs and we want to have control over the firewall at this site. We  are going to remove the ASA at site B, have the telco change the IP from to (so to minimize issues with internal  clients using the current default-gateway of the ASA.).  At site A,  again we want to keep the ASA in place and keep its inside IP address.

Here  is the question: Do we simply need to add a static route on Site A’s   ASA for any traffic needing to reach Site B. Like so - 

route inside 1

Will  this work on the ASA? We need to make sure traffic can hit the ASA @ site A on the  inside interface and trafiic will forward to the MPLS VPN router which  then handles the traffic. Too, will it cause any problems in  bi-directional flow between the two sites?

Thank you for taking your time to review!

This command

route inside 1

should read

route inside 1

However, hairpinning on the ASA won't work:

Very good at explaining why...

oops, you're correct.  But will adding the static routes work or will i need hairpinning? Thanks for the help!

Re: Inside Static Route

Traffic will flow in/out the same interface - that's hairpinning.

Not supported on ASA - details mentioned on the link I posted.
