port mapping converting gui to cli

samdilloway · ‎09-11-2014

Hi,

I am having an issue with a new office LAN implementation and I was wondering if anyone can help.

The current setup has a Linksys router and there are port mappings for the servers for a inside and outside port. This has been input via GUI. I am upgrading to a 3845 router and have converted the GUI input to Cisco CLI. This however does not work and the LAN does not behave as it did before.

The Linksys GUI input is attached.

and I have done this conversion;

ip nat inside source static tcp 10.155.62.55 21 91.108.160.100 21
ip nat inside source static tcp 10.155.62.55 88 91.108.160.100 88

ip nat inside source static tcp 10.155.62.46 8081 91.108.160.100 91
ip nat inside source static udp 10.155.62.46 8081 91.108.160.100 91

91.108.160.100 being the outside public address.

Can anyone see what I have done wrong?

Thanks.

Hi @samdilloway,

A few questions for you:

Did you check if those servers can go to the internet?
Is the NAT functioning properly when they go outside?

Here is a link of a page with the step-by-step process of the port mapping configuration. Make sure you're doing it exactly like that:

Also, a link of a TSHOOT page for the same problem:

http://kb.linksys.com/Linksys/ukp.aspx?pid=80&vw=1&articleid=22385

To be sure, the problem that you have is that users from outside cannot access to the services your mapping, right?

Let me know your answers.

HTH.

Don't forget to rate.
