FreeBSD serious problems with vnet on if_bridge (probably ARP related?)

Hello, I ran into serious trouble setting up a FreeBSD 12.3-RELEASE-p5 host having a second NIC and vnet jails attached to that second NIC (basically, the host is a recent Xigmanas with Bastille jails). Hopefully, I can gather some answeres here. The host is comprised of two NICs, em0

NPTv6: prefix doesn't change in IPFW when prefix changes on dynamic interface

Hello, running a small routing/firewall applicance based on 13-STABLE and IPFW, I face a problem with NPTv6. The external IPv6 is changing dynamically. While ipfw in-kernel NAT catch up with dynamical changes of the IPv4, NPTv6 doesn't seem so. I'm neither an expert in networking nor IPFW.

IPFW: IPv6 and NPTv6 issues: multiple IPv6 addresses confuses IPFW

Hello, running a small nanoBSD firewall/router appliance, the WAN interface (tun0) is confugred via SLAAC when it comes to IPv6. The allpliance is running in-kernel compiled IPFW. The OS is FreeBSD 13-STABLE, compiled on a recuurant weekly basis. On a 24 hour basis, the ISP changes the IPv4

Hello, I've got a problem with recent CURRENT, running vnet JAILs. FreeBSD 15.0-CURRENT #28 main-n267432-e5b33e6eef7: Sun Jan 7 13:18:15 CET 2024 amd64 Main Host has IPFW configured and is open for services like OpenLDAP on UDP/TCP and ICMP (ipfw is configured via rc.conf in this case, host
