I have not tested this,but I dont think there should be any issue.It is not nessasry that we use only outside interface as lower security interface.We can change the security levels so it does not make sense to keep the VPN binded only to outside interface.
I also would like to know if the vpn endpoints can be the outside interface. In this scenario, we are using the intranet(that is the tunnel is actually the LAN). Does the pix allow traffic to cross the its interfaces if the endpoints are on the far side.
Also, I would like to know the static nat and or global nat command necessary to not affect the existing production traffic in the original scenario when the endpoints are the inside interface. Is there any reference anywhere similar to this scenario?
According to your reply, we can keep the inside as higher security, is this correct?
