Hi Rick,
sho ip nat trans shows the ICMP translations when I ping from the switch's
SVI int to the comm server.
But when any of the IPT tries to communicate with the server, nothing
appears in the NAT translations, which means that the packets are not
translated at all...

What does the show ip nat trans give?
My example:
R1#sh run | i nat
ip nat outside
ip nat inside
ip nat outside source static 172.16.13.2 172.16.20.1
R1#
R1#sh ip nat translations

Yea sure:
Here's the packets:

d=10.237.75.195(FastEthernet0/0.3), len 41, rcvd 3
Aug 4 13:50:52: UDP src=5000, dst=4100
Here's the nat conf:
ip nat outside source static 10.239.98.55 10.237.75.195
and couple of inside and outside on int.
I'm trying to nat global address 10.239.98.55 to 10.237.75.195.
The nat is working properly for ICMP... but the ipt traffic is not flowing
to the comm serv.
thx
