Hello. There is a 1400 gateway with anti spoofing issues.
I added a new subnet, associated it to a couple of interfaces, and it worked, for a couple of days. Then, traffic to that new subnet began to be dropped because of an anti-spoofing alert. There is the global property which could be disabled, but I found no other tool to troubleshoot or solve it. There are 2 other LANs on the same gw, and no problem with them.
Thank you very much.
