First of all, here is my current setup: In rc.conf: set -- $(/sbin/ifconfig -l ether); eth0=3D$1 eth1=3D$2 eval "ifconfig_${eth0}_name=3D\"eth0\"" eval "ifconfig_${eth1}_name=3D\"eth1\"" ifconfig_eth0=3D"-tso -lro -rxcsum -rxcsum6 -txcsum -txcsum6 -vlanhwta= g=20 -vlanhwtso up" In rc.local: vm switch create public vm switch add public eth0 ifconfig vm-public inet 0x629e8b41/27 ifconfig vm-public inet6 2605:2600:1001::41/64 route add default 98.158.139.94 route add -inet6 default 2605:2600:1001::1 This works just like a number of previous attempts. I can ping any site = in=20 the world but, other than to the host, I can't connect by TCP. My test i= s=20 ssh. But now I just noticed that I can ssh into one other server on my=20 network. The only difference that I can find is that the one that I can = connect to has a HP NC382i DP Multifunction Gigabit Server Adapter - bce(= 5).=20 It's the only one in the network with that adapter. The host and many = other servers are bge(5). Here are the ifconfig entries: eth0: flags=3D8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric= 0=20 mtu 1500 options=3D80088<VLAN_MTU,VLAN_HWCSUM,LINKSTATE> ether 14:02:ec:31:60:d0 media: Ethernet autoselect (1000baseT <full-duplex,master>) status: active nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> vm-public: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 = mtu 1500 ether 1a:d8:8b:3e:51:87 inet 98.158.139.65 netmask 0xffffffe0 broadcast 98.158.139.95 inet6 2605:2600:1001::41 prefixlen 64 id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15 maxage 20 holdcnt 6 proto rstp maxaddr 2000 timeout 1200 root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0 member: tap0 flags=3D143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP> ifmaxaddr 0 port 8 priority 128 path cost 2000000 member: eth0 flags=3D143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP> ifmaxaddr 0 port 1 priority 128 path cost 20000 groups: bridge vm-switch viid-4c918@ nd6 options=3D1<PERFORMNUD> And the remote: bce0: flags=3D8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric= 0=20 mtu 1500 options=3Dc00b9<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN= _HWTSO,LINKSTATE> ether 3c:d9:2b:f9:e2:10 inet 98.158.139.77 netmask 0xffffffe0 broadcast 98.158.139.95 inet6 fe80::3ed9:2bff:fef9:e210%bce0 prefixlen 64 scopeid 0x1 inet6 2605:2600:1001::4d prefixlen 64 media: Ethernet autoselect (100baseTX <full-duplex>) status: active nd6 options=3D21<PERFORMNUD,AUTO_LINKLOCAL> That PROMISC flag looked promising but turning it on on other servers did= n't=20 help.
