NAT with H323 on Cisco2800 Router

[Sarasaqlain]

Hello,I have configure NAT for H323 packets so that when call goes out of router it should be a natted ip address for outside world but its not happening.

Could some one tell if this is possible.:

NAT Configured:-

ip nat inside source static 10.0.10.10 10.88.1.80

And i have applied it to the interfaces aswell.

But when i see the traceroute:-

Internet Protocol Src:-10.88.1.80 dest:- 10.203.5.30(which is wrong)

TCP1720 is opened and there is no firewall inbetween which is blocking this.

Anyhelp on this would be appriciated.

Thanks in advance.

Hi

Not sure which way you want it. Do you want it to appear as 10.0.10.10 or as 10.88.1.80.

If you want 10.0.10.10 to appear as 10.88.1.80 then your NAT is correct. If other way round then

ip nat inside source static 10.88.1.80 10.0.10.10

Also be aware that NAT and H323 do not always work well with each other.
