KB ARTICLE

See above Kb article about this FW Log Warning on FW Ver 1047 and earlier.
If that's not related to your entries, I'm sure someone will come along to help.

 

hey above KB article is related to 1047 or earlier versions .but thx anyway.

 

I thought I had read that some FW Versions were not updating correctly as they were introduced so I wondered if you had the latest ESS Ver but (somehow) an older FW Ver. Good Luck.

I too have 1050 and am still experiencing the same exact problem as you. I am getting 2 messages in my firewall logs that do NOT comply with the KB.

Is it a very minor bug that I should not worry about at all and ignore totally or should I annoy them with a customer support ticket? I'm sure they must know it's going on. I just don't know what I should do. Could use some advice to put the matter to rest entirely.

Here are the 2 messages (I don't even know what they mean truth be told - looked it up and all Greek to me):

a) Incorrect TCP packet checksum

b) Incorrect IP packet checksum

Thank you in advance. You guys are the greatest.
