I have 3 WHR-HP-300N routers at 3 different locations and all three seem to block SNMP trap messages sent through them. I have a central SNMP server that receives the traps, and I just realized that all 3 sites with these devices are not receiving any alerts. I have tried both the 14512 and 14998 DD-WRT firmware as well as the generic 14896 firmware, and all three are blocking the traps. I swapped the router at one location out with a Linksys WRT-54GL and it is allowing the traps through just fine, without making any changes to anything else on the network, so I feel confident that it is in the router, and not anywhere else in the system. I even setup a test site, and played around with various settings on the WHR-HP-300N and was unable to get it to ever allow the packets through.
Has anyone had a similar issue, or have any ideas as to why these are being blocked?
