Hartmann --- I checked today on other systems I claimed having the very same configurati= on successfully running. That wasn't true. In the other, working case, the physical NIC, bge1 in one case and igbX in another case, the physical NICs = are not assigned with an IP address, they simply offer the physical access to t= he network via switches. The main host carrying the jails itself is then attac= hed to another physical NIC, which doesn't route locally. So, in the case I reported here, the jail-carrying host itself has physical= NIC igb0 as its NIC and applied with an IP address, but the jails and their epa= irs are member of the same bridge, to which this physical NIC is also member - = as shown. Routing/gatewaying is disabled. All hosts do have a default router. As reported, pinging from a jail running OPEN ipfw other epair members of t= he same bridge, the outside world (i.e. 1.1.1.1) or the router/gateway, works fine. Pinging from any jail on that bridge to which the physical NIC of the host is member of doesn't work, UNTIL I ping from the host to which the NIC= is associated any of the jail's on the bridge - it seems ipfw (also running in WORKSTATION mode on the host) is the opening the flow. From then on all net= work traffic is possible and flowing. I consider this bahviour a bug. --=20 You are receiving this mail because: You are the assignee for the bug.=
