I realize there are other posts on this, but one ended with the person buying a new router. Does anyone have any new insights? This is crazy that I just can't add a port forward without an error.
I was going to insert the images but when I click the insert image icon all i get is . Have no idea what I'm suppose to do with that.
Basically I am trying to add a port forward and when I hit save I get "412 - Request Entity Too Large". Tried it using Chrome Edge, IE, Firefox and remotely using Opera. All yield the same. I'm not onsite now and I'm afraid if I set it to factory defaults I won't be able to access it again as the computers may not pick up the new ip address (since I'm using 192.168.1.1 sub net and it uses 192.168.0.1 by default) and I don't think there is a way to factory reset it and keep remote management enabled.
Without the port forward, the router is useless to me. So I solved one problem by moving to this router and created a new problem.
Hardware version is C2, Firmware Version is 3.02 dated I think November 21, 2014. Did I do a factory reset after the firmware update, probably not, most routers don't need that. Anyways, if anyone has found a resolution that would be nice.
