I have a Cisco 837 running a site to site VPN with a network translation to allow the incoming request for 172.20.14.X to be translated to 10.5.251.Y. Where the 10.5.251.Y computers are behind the 837. The commands we have that work on the 837 are as follows.
ip nat inside source static 10.5.251.249 172.20.14.100 route-map SDM_RMAP_2
ip nat inside source static 10.5.251.40 172.20.14.101 route-map SDM_RMAP_3
ip nat inside source static 10.5.251.10 172.20.14.102 route-map SDM_RMAP_4
I want to be able to replicate this with a PIX 501 but am unable to find a command which will allow the above rules.
