Trusted (allowed IP) being blocked by UFW

Asked by Andrew on 2014-11-10

Why would UFW block an IP to port 443 is such IP is listed under UFW allow ?

The logs reveal they are almost always TCP RST packets, TTL is around 54 -59.

BTW, the allowed IP is shared by a medium sized office connecting to a webserver so multiple connections are occuring at once. I'm guessing there is either A) some sort of collision or corrupted data being received OR B) two many connections that are being rate limited somehow.

Ufw can process masses of data so a relatively small office is no problem.

What is the output of:

lsb_release -a; apt-cache policy ufw gufw

Oneiric is no longer supported in any way. It is EOL. I suggest you wipe Oneiric off and do a clean install of Trusty. Trusty is LTS and supported til April 2019.

Can you help with this problem?
