Because I felt like it and it wasn't too hard. I have a PyDECnet version that can handle not just IPv4 but also IPv6. It's on node PYTHON right now and on the map server 28NH (at akdesign.dyndns.org). This applies both to the web interface and also to the various IP-based datalink protocols. I've tested Multinet, GRE, Ethernet (UDP bridge) and DDCMP. If anyone is interested in using this with PYTHON, let me know. Unfortunately dyndns.org doesn't support IPv6 records well; I can enter one manually but it disappears after a while for reasons I do not understand. It's there now.

I can't wait to try it out..... except that I bought a new Cisco small business router (RV340W) and this has introduced a whole load of IPv6 woes. LAN -> WAN initiated calls work fine...... except that windows hosts eventually forget the link-level address of the router and the router itself throws up something worrying in its logs about being unable to advertise the router address. WAN -> LAN initiated calls don't work at all. They don't even get as far as tickling an access rule's logging setting. I'm really annoyed that changing any firewall rules (v4 or v6) causes all stateful connectivity to be forgotten and everything is dropped. Even Draytek Vigors didn't do this unless the rule change was pertinent to particular connections. What really really annoys me is some linux daemons (DHCP server) being terminated and restarted every 15 minutes or so.... almost as though it's a quick a dirty fix to some sort of bug they couldn't figure out. Sorry for the rant. I just remember when Cisco and quality appeared to be two different spellings for the same concept. I'm sorely tempted to roll my own.

I have IPv6 turned off on my network - that's a can of worms that I just don't need. Someday I'll have to deal with it, but not today :) BTW, I don't know about the RV340 family, but the 32x series has a fair number of known exploits. Be sure you upgrade to the latest firmware! Bob

I use a lot of Cisco enterprise kit. The SOHO stuff as mentioned is just rebadged Linksys and similar - it's in no way similar in any fashion.

When I'm not using Cisco, however, my absolute favourite vendor is Ubiquiti. I use a whole range of their products.

The edgerouter 1.x firmware ships with Python 2.7.3 and the 2.x firmware ships with Python 2.7.13.

I implemented an Edgerouter at home to replace my Linux box which acted as a firewall for years. The fact that the router is now disjointed from any of my servers is a good thing, because I can upgrade/change/replace firmware and config on my router without concern that I'll break any additional network functionality. I don't want a router update (which is currently a seamless and clean experience) to become more of a "server" update. But please don't let me convince you that it can't be done, because I feel that it most certainly could be done.

The 1.10.11 (which is what I run on most of my devices) has been stable and unpatched since March 2020. It's also pretty much guaranteed to be the last 1.x release The 2.x series is under regular release (2.0.9 came out 19-NOV-2020).
