PFSense adding a tonne to the header

@cool_corona I can try that but there is a bit of new info come to light. Speaking to my IT manager he tells me the connection is reset by the VM as the heartbeat message is not being received. It looks like this is being intercepted by pfsense somehow.
Does this sound feasible?
-
The heartbeat message in the Teams connection?
That would have to be something over a connection the client opens. pfSense would allow all outbound traffic by default so it wouldn't block it unless you have additional outbound filtering in place. Or something dynamic like Snort or pfBlocker, potentially.

@stephenw10 I have fixed it. Now this may not be anything related but sure as hell made the performance of the whole system improve - unbeknownst to me one should never run power and ethernet cables side by side.
I fixed that and have not had a problem since. Touch wood. -
Mmm, that should not really be a problem unless you're at the very edge of the capability. Trying to run 10G over cat5e for example. Seeing mains interference is probably because the cable is wired incorrectly. If one of the twisted pairs in the cable is not wired as a twisted pair (would have to be two pairs with wires swapped) you will see far worse common mode rejection.
-
@stephenw10 I concur have never really seen power next to runs be an issue. Worked in a production plant for many years - and we had all kinds of high electrical noise sorts of equipment and lots of power runs everwhere. I mean we never on purpose ran next to power lines for any serious lengths of a run - but many places where they shared same space and never saw any sort of issues.
-
@stephenw10 Yes 100% agree. I doubt my setup should have affected this except for a 0.5m run of ethernet and 240V AC. And yes I know (a bit) about common mode rejection. Electronics 204 if memory serves correctly, my electronics lecturer was a real spanner which is why I remember - but hey - problem gone!!
-
Well I'm glad you were able to find it because I would not have suspected that for a second!
-
Perhaps reseating the Ethernet plugging during testing provided a better connections.
-
@patch I spoke angrily to it as well. That should have left it in no doubt as to what I expected.
-
@stephenw10 hehe who knows. I optimise radio networks for a living, and sometimes I turn to the next guy and admit I have zero idea what I did to fix something, but fix it I did, and on to the next one...
In this case VLANs. Boot camp time.
-
@youcangetholdofjules one final question - can anyone recommend something better than Powerpoint for drawing a network map. I do have Solarwinds for a different purpose but that seems like using a low yield nuke to open a door with. I need a key.
Network size is around 15 pooters, but using VPNs, bridges and VLANs, so it looks like spaghetti.
-
I have used draw.io before. But usually because it's quick and easy not necessarily 'better'. It gets the job done.

In the MS world visio is the tool for network drawings - use it all the time, but its not free.

@johnpoz thank you both for the reply
