Netgate 4200 Ethernet Port Numbering?!?!
-
I just received and configured a new Netgate 4200 appliance replacing a 4100. On all my prior Netgate appliances the ethernet ports were sequenced left to right matching igc0 thru igc3. On the new 4200 they are reversed with the ports labeled 1-4 left to right but mapped to igc3 thru igc0. Is this normal and expected? It is counter-intuitive and also means the configs no longer match between the new 4200 primary and old 4100 backup firewalls. It also delayed getting the firewall working since everything was reversed. I also noticed the Ethernet cable connector tabs are at the bottom of the jacks instead of the top. My first thought is the 4 port Ethernet assembly was installed upside down.

Use notepad++ to find and replace the interfacea in the config. Our primary is an 8200 and our backup is a 5100. We just download, find and replace for the interfaces and upload. We have a recorded macro in ++ that produces a 5100 config from our 8200 in about 15 seconds.

@cswroe Yes, I know how to adjust the configs. That doesn't answer the question as to why they are reversed on this 4200 versus very similar 4100 and why the Ethernet connector tangs point down instead of up now. I am looking for the answer if this is true for all 4200 or if mine is anomalous.

I dunno about "expected", but it's documented to be that way in the fine manual. And yeah, my 4200 is like that too.

Nope they are supposed to be like that. It couldn't be installed upside down, the connectors are only on one side.
The NIC ordering is dependent on how they are parsed by the OS. They are labelled independently of that.

I'm guessing that labels on the box are not tied to physical connectivity inside the box.
Physical traces got to specific places so that mapping is always consistent, but as the OS comes up, detection/initialization of hardware may vary (timing). So an external rj45 labeled eth0 is physically connected to the same place but OS may dectect the physcial thing as igc0 one boot, igc2 the next.
As long as the configuration always references eth0 it shouldn't matter to the user because "eth0 is eth0" -
Well the NIC order should always be the same between boots on the same hardware. It can vary if an additional NIC is added and is not always easily predictable.
