Bullard" , openvpn-devel Ok, I=E2=80=99ll only discard the irate part ;-] I had not considered the extra work and code required to maintain both vers= ions. But I get it now. Here is the unfortunate position this puts us in: We use OpenVPN for connection from 1000=E2=80=99s of devices located at cus= tomer facilities back to us. These devices/software have a lifespan of grea= ter than 10 years and most are extremely expensive (not easily replaced). S= o a large quantity are incapable of ipv6 (and frankly many customer facilit= y networks are not fully functional with ipv6). Also some of the devices/so= ftware at our end that interface with those legacy customer devices are als= o not ipv6 capable.=20 So if OpenVPN lost ipv4 support anytime soon, we would be in a world of hur= t. There is much more detail about all this, but I wanted to keep this a s= hort email.=20 Thanks for listening.=20 Marvin > On Apr 1, 2018, at 11:39 AM, Gert Doering wrote: >=20 > Hi, >=20 >> On Sun, Apr 01, 2018 at 11:19:57AM -0700, Marvin Adeff wrote: >> Think of us poor mail list lurkers.
