Hi,
Long time lurker here...
I tried adding a NIC to my Sophos UTM running under vSphere ESXi 5.1, and that pretty much killed the firewall. I managed to bring it back up by deleting recently added NIC, but the behavior is definitely strange. So now to the explanation of what I observed:
1. Current config: 3 NICs VMXNET3 (eth0, eth1, eth2)
2. Added 4th NIC VMXNET3, rebooted the firewall - eth2 disappeared, new NIC shows up as eth3. So ended up with eth0, eth1, eth3. Firewall is dead.
3. Analyzed boot messages in the log. Here is where it gets funky:
vmxnet3 0000:04:00.0 eth0: NIC Link is Up 10000 Mbps
vmxnet3 0000:0b:00.0 eth1: NIC Link is Up 10000 Mbps
vmxnet3 0000:13:00.0 eth2: NIC Link is Up 10000 Mbps
so it does detect eth2. Then it detects a new NIC eth3
vmxnet3 0000:1b:00.0 eth3: NIC Link is Up 10000 Mbps
and things go haywire:
irqd[3642]: eth0 ether (mac address of eth0) <broadcast,multicast> group 0
irqd[3642]: rename3 (mac address of eth2) <broadcast,multicast> group 0
irqd[3642]: eth1 ether (mac address of eth1) <broadcast,multicast> group 0
irqd[3642]: eth3 ether (mac address of eth3) <broadcast,multicast> group 0
Ethernet adapter eth2 gets the name "rename3" and doesn't show up under adapters list in Sophos.
Any Linux gurus who know how to fix it? I'd like to avoid rebuilding the firewall if possible.
