Error regular translation creation failed

[michael.olson]

I am currently getting this error on my 515 log. Can someone please tell me what I need to do to resolve it. I have two pix 515 firewall Primary and Failover. I am also using stateful failover. Here is the whole error. 305006: regular translation creation failed for udp src inside:x.x.x.x/137 dst Failover:x.x.x.x/137

this is not a valid request as the destination packet is for failover interface, moreover its a netbios request, you need to check why the destination is for failover interface

I will look into it. It isn't anything serious... correct. Just informational?

[abinjola]

I can see the source port and the destination port to be the same..could be some kind of flooded traffic directed towards pix/attack

Do you see the request from one pc ? and does it happen rarely or continuously ?

[michael.olson]

Every once in awhile but multiple times a day.

[abinjola]

well don't worry you are safe as firewall is dropping that packet

please rate if my posts my help
