network problem (isolated cases)
hi forum , I have a couple of isolated cases, the vlan of my servers has free exit through the firewall, I can go anywhere, a few days ago I had a vm with windows 2012 server and did not go online, this vm was for a long time fine, looking in the firewall if I was blocking and did not find anything, the last thing I did was change ip vm and went to the internet without problems.
I started thinking, what happened here?
annex the rules of that vlan and the traffic of the vm with tcpdump
I do tests with the dns when consulting registries of other domains from the vm and
these resolve well, but I can not surf the internet.
