Route external port to internal different port RV325

Hello,

 

We have a company that wishes to connect to some of their machines within our network, through our Cisco RV325 Router. They want to connect to different machines according to which port they connect through. However, the local machine ports should always be the same. They are looking for this configuration :

(external_vendor_ip_address):9100 -> (local_ip_address_of_machine#1):9100

(external_vendor_ip_address):9101 -> (local_ip_address_of_machine#2):9100

(external_vendor_ip_address):9102 -> (local_ip_address_of_machine#3):9100

 

I would like to limit these connections to the external IP of the vendor, and forward the right port to the right machine.

I found "Port Address Translation" which seems to allow me to translate, for example, outside_ip:9101 to local_ip:9100, but I can't find how to limit the outside IPs to a single one.

 

Any help would be appreciated.

Thanks

Hello,

 

annoying indeed, as you can do one-to-one NAT and Port Address Translation, but not both together. In IOS, it would be something liek:

 

ip nat inside source static tcp 192.168.1.1 9100 10.10.10.1 9001 extendable

 

I don't think you can do that on an RV325...
