Welcome to issue #6 of Packets Down Range. The thing I am excited about lately is the 100 Gig passive mux by solid optics. One of the hats I wear is running an IX. We are always looking for ways to best utilize our dark fiber assets to increase data rates. Keep those tips and articles coming. I am working on the Patreon edition, and it will be released shortly.

WIFI calling port forwarding
Recently I came across a need to do some port forwarding for wifi calling. I have assembled a resource guide to help you if you need to do such things. IPSEC should be allowed per RFC 5996 https://tools.ietf.org/html/rfc5996 for all wifi calling Verizonhttps://community.verizonwireless.com/t5/Verizon-Wireless-Services/What-are-the-wifi-calling-firewall-ports-and-destination-IP/td-p/1080659UDP ports 500 and 4500 open to sg.vzwfemto.com and wo.vzwwo.com TMobilehttps://www.t-mobile.com/support/coverage/wi-fi-calling-on-a-corporate-networkIPv4 Address Block: 208.54.0.0/17 and 66.94.0.0/19:UDP Ports 500 and 45005061 for SIP/TLSTCP port 443 and 993Also whitelist the CRL server for DIGITS OTT and WFC 1.0: crl.t-mobile.com 206.29.177.36 AT&Thttps://www.att.com/support/article/wireless/KM1114459/UDP Ports 500 and 4500TCP...

This morning I had a Mikrotik CCR1016 where I had to change the router ID, which caused all the sessions to reset. The following is a screenshot of the time it took to re-learn all of the peers. Obviously, the smaller prefixes were learned pretty quickly. It took about 10 minutes to learn two full IPv4 route tables and about 5 minutes to learn the IPv6 routing tables. This is why I always get full routes plus a default from the upstream when...

Normally on a peering exchange, all connected parties will establish bilateral peering relationships with each other customer connected to the exchange. As the number of connected parties increases, it becomes increasingly more difficult to manage peering relationships with customers of the exchange. However, by using route servers for peering relationships, the number of BGP sessions per router stays at two, if the IX has deployed redundant servers.

This was originally posted at: https://www.mtin.net/blog/why-every-isp-should-be-deploying-hap-lite-to-customers/ So Mikrotik has a very cheap hAP Lite coming out. This is a 4 port, 2.4 b/g/n router/access point which retails for $21.95. Baltic networks have pre-orders for $18.95. Why should you deploy this little gem and how? We have found over the years routers account for more than half of the support issues. In some networks, this number is closer to 80-90%. Whether it be a substandard router, one without of date firmware, or poor...
