Wifi Calling Firewall Holes to Punch
by Lyden, John C 17 Jul '20

17 Jul '20

Hey gang. We're setting up a unified wireless network for the students here, and to get around the issues with Nintendo and NAT we devoted a large chunk of public IP space to them. We're aware that this is causing issues with wifi calling on Verizon, TMo etc because it appears they initiate the SIP session inbound. Does anybody have a handy list of IP blocks and ports? T-Mobile had a decent page but other providers just said "open up 4500 and 500" and our ISO guys don't like that. Thanks if someone can help. John C. Lyden Manager of Network Infrastructure, Infrastructure Services Division of Information Resources & Technology, Rowan University

by Mehmet Akcin 16 Jul '20

16 Jul '20

hey there, I recently have come across this http://ping.pe/ website, I have no association with this but it's pretty awesome. This made me wonder what other tools out there which I do not know about it. what are your favorite network troubleshooting tools? In addition to ping.pe, I like https://bgp.he.net but would love to hear your thought about other tool recommendations as especially the ones that are distributed. Mehmet

>> what are your favorite network troubleshooting tools? I thought I'd add a little data to my first response: To watch the network in real time with syslog, which puts messages in /var/log/router.log: tail -f /var/log/router.log | egrep -vi 'terms|I|do|not|want|to|see|SyncConfigOK|SaveConfigSucceeded|LogFile|etcetera|etcetera' To look for a problems on router1: grep -i router1 /var/log/router.log | egrep -vi 'terms|I|do|not|want|to|see' | less scott ps. it's free. no cost. low learning curve. easy and fast.

CPE and bufferbloat
by Michael Thomas 15 Jul '20

15 Jul '20

Given the new stresses of teleworking on the infrastructure, have providers been getting more calls about "the internetz are slow"? And if so, can you attribute any of it to bufferbloat? Anecdotally, I once had to hunt down a problem where the network was slagged because a friend was downloading a big game and it took me like over an hour to figuring out what was going on. I got a new router and flashed openWRT and turned on the shaping and it went from really bad to pretty unnoticable. Most people are probably just going to contact the help desk. Of course anything in the upstream would have been even worse, which of course things like Zoom tickle heavily. Mike

Looking for an admin at Solarwinds MSP/Mail Assure
by Mark Spring 14 Jul '20

14 Jul '20

Does anybody have a contact at Solarwinds MSP where I could troubleshoot some issues with receiving messages from their Mail Assure platform? We have several users/domains that cannot receive messages from them and I don't see any connections from their servers at the TCP level that I can troubleshoot. It seems like they are holding onto old records but the admins that hold the service contract have not been able to produce any kind of logs from their support. When they send a message they get 5.0.0 response, but the same thing happened when they typ-o'd the domain which tells me it's a bad lookup on their server. I'm happy to work with anybody at solarwinds MSP or anybody else that might be able to shed some light on this. My users are just having issues receiving the message from solarwinds customers but I'm happy to put any amount of my resources into getting this resolved.
