ZeroTier does not appear to pass through SFC

Hello,

I’m trying to send Zerotier through an SFC tunnel to an SFC exit node from a BR1 Max 5G. When I turn SFC on, pings through my tunnel stop and timeout. Everything is fine when my SFC tunnel is disabled. I can’t for the life of me figure out how to get this to pass. Is there a block rule in place on the SFC VPN to block Zerotier or is it just something that I am missing?

Any help would be appreciated.

I would try reducing the MTU in ZeroTier.
