Three OP routes are connected using vpn through ipv6
Network situation:
a--b--c (a and c is offices, b is the headquarters )
(a:192.168.1.33/27;ipv6
b:192.168.1.97/27;ipv6
c:192.168.1.65/27;ipv6)
(The ping mentioned below refers to 192.168.1.X:)
When vpn establishes a connection, b cannot communicate with a or C, but A/C can ping b, after a/c ping b, b can ping a, or c
(After a ping b, b can ping a, but still can’t ping c. The same goes for
After c ping b, b can ping c, but still can’t ping a,
That is, whoever pings b can ping whoever b)
However, after a period of no data exchange, the problem reappeared.
Please help, and what configuration do I need to provide?
I hope I can understand my question, thank you
I think you should really try WireGuard: server + client + site-to-site.
It can solve the current issue and simplify the configuration by an order of magnitude.
