Firewall/NAT/1:1/Edit - wont accept internal IP address format?!?
I have a few 1:1 NATs that I've been using for years. I needed to add another. I set up an unused WAN IP on the External subnet IP field. I had my WAN interface selected. For the Internal IP part I select Single Host and put in the internal IP address of the machine (as I have done many times). This time it keeps telling me "Please match the requested format" (see attached snapshot).
BTW: I'm running 2.3.2-RELEASE (amd64)
Here's a more appropriate link.
