Getting Openvpn on 2.8.1 to work with Yealink T21P E2 VPN
I've been using old PFsense, something like 2.4.X or 2.5.X. I have openvpn remote access (SSL/TLS) installed and with certs in the phones they connect magically onto my private network and onwards to my IPPBX. While this function is not critical but it makes the office phones very useful when you are on the road etc. of course the alternative is soft SIP phones
I've upgraded my PFsense once before and had nightmares with the VPN so I decided to stick with the old version. Recently I had some free time and I thought maybe with the help of an AI..... XD I might get it to work. After tinkering with it a few days, I've pretty much given up. I dont mind paying for a support to fix this but I fear its all pointless as my hardware are so old that I need to revert back to the old version
I hope someone here can give me a pointer or 2 as I've tried with both lowest RSA and SHA1 and it did not work.
Also seems like older pfsense are no longer available for download and if anyone has link to the older version it would be greatly appreciated
