Hi,


Router : 877W & 857

IOS : 12.3(8)YI2 & 12.3(8)YI3


I'm new to IOS, so I may be asking something that has been documented, however I cannot find it, so......


Can anyone confirm if its possible to perforn a NAT and PAT for inbound connections at the same time? If so, a pointer to the doc's or command would be helpful.


Basically I want to be able to RDP to multiple machines using a different port number, but not have to change the recieving systems default port number.


For example:


Global Address1:33101 --> Inside Address10:3389

Global Address1:33102 --> Inside Address20:3389

Global Address2:33101 --> Inside Address100:3389

Global Address2:33102 --> Inside Address200:3389


Thanks in advance.

Try this:

ip nat inside source static tcp Inside-Address.10 3389 Global-Address.1 33101 extendable

ip nat inside source static tcp Inside-Address.20 3389 Global-Address.1 33102 extendable

ip nat inside source static tcp Inside-Address.100 3389 Global-Address.2 33101 extendable

ip nat inside source static tcp Inside-Address.200 3389 Global-Address.1 33102 extendable

Hello Tekha,


Thank you very much for the fast response & commands. I had tried something similar, but I must have made mistakes, since IOS kept responding with a message stating that the port 3389 was already being used. I got no such message with your commands. I will verify functionality and advise accordingly.


Once again thanks.
