Cisco 877 NAT Routing Help Needed

Unanswered Question
Apr 26th, 2008

Hi people, im new here. I have got a Cisco 877 with Advance Sec ISO. I have configured it for internet access and I am able to connect and surf the internet on all PCs on my inside network. The next thing I need to be able to do is run a webserver and ftp server inside with access from the WAN. So my question is. How do I setup a port forward for web port 80 and ftp port 21 to my internal server 192.168.1.3. Any help would be fantastic.

Cheers

Will

Thank you very much for the quick reply. I have attached my conf, can you tell me if it looks right. I have got access to the webserver now, but not the ftp. So close.

Thanks again.

Adding the following line.

ip nat inside source static tcp 192.168.1.3 21 interface Dialer1 21 extendable

Comes back Invalid input detected.

Sorry, I might be being silly, but still no joy. It just gets Invalid input detected and pointing to the word extendable.

Hi,

It was nothing missing, it was my friend who was testing for me from external typing in the wrong IP address for the FPT. So user error. NAT is working like a dream. Next fun thing is the VPN, but will be leaving that for another fun day.

Thanks again for the pointers, very helpful.
