Hello,
I have a few OpnSense routers connected with ZeroTier (version 1.10.2), all with public IPs, and traffic is flowing/routing properly. Using it for both site to site traffic and remote gateway for policy routing traffic over and out of a central location.
On either 30, 60, or 90 second intervals (seems to always be increments around 30s) i see latency spiking from the sites from the normal 30ms to 300+ for a single ping.
Wondering if there a config option or settings other people use who don’t have this issue, here are some following items i have tried and configs:
- Set firewall to conservative profile
- Opening 9993/udp (no effect)
- Shaper rules (little/no effect)
- Confirmed no relays
- MTU lowering (no effect)
Best working local.conf
