24.7 Production Series / My first OpenVPN, ipv6 issues
« on: September 05, 2024, 10:28:19 pm »
Hi all,
I'm configuring OpenVPN server on OPNSense, I already done it successfully on some linux machines some year back and now it is my first time on OPNSense.
Client connection hangs at:
In the OpenVPN log I see the following error repeated every few seconds:
It seems to be the same problem described here: https://www.reddit.com/r/OPNsenseFirewall/comments/1adzr5y/openvpn_setup_instances_getting_ipv6_address_error/
I tried to look for the setting to disable IPv6 in the Instance settings page but I can't find it.
What should I do?
