Source NAT from outside

PIX 560E 6.3(5)

I need to take inbound communications from a remote VPN site and have them come out of the inside interface of my PIX and appear to originate from that inside interface.

I have:

global (insdide) 1 interface

nat (outside) 1 access-list acl_vpn outside

access-list acl_vpn permit ip host <host from the outside> <network it needs to access> <subnet of inside network>

sh xlate seems to be working as I get:

PAT Global <inside interface address>(17) Local <outside ip> ICMP id 147

I get no replies from the pinged box though. I can ping it directly from the PIX itself though.

Re: Source NAT from outside

Hi .. sometimes using pings is probably not the best way to test connectivity across a firewall specially if you are using NAT and don't have ICMP inspection enabled. I suggest enabling icmp error inspection using - fixup protocol icmp error - Also try using a different application i.e telnet, RDP or something like that.

I hope it helps .. please rate it if it does !!!
