Netgate 4100 - Current WAN reconfigure to a 2.5Gbps

[BennySoh]

Dear Community,
My current Netgate 4100 WAN port is on 1Gbps and I will be receiving an ISP ONT that supports 2.5Gbps.
Will I be able to make use of 1 of the unused 2.5Gbps physical port to be assigned to this WAN ?

Would such a change be possible and will my current backend network be intact and be able to access the Internet with such a change.

Many thanks for your insight on this.

@BennySoh You can use any port for any function including WAN.

You can reassign WAN to the new port in Interface Assignments.

@SteveITS , Thanks Steve, my worry is, would this change from a current working WAN to a 2.5Gbps port disrupt all my current backend network setting, rendering it inoperable ?
Thanks for your patience on this.

@BennySoh If you don't change anything on LAN or other interfaces I don't see there would be any problems. At the point of the interface reassignment I'd expect open connections to drop.

@SteveITS, Thank you very much for the pointer, I appreciate the pertinent tip and look forward to better speed on the reassigned WAN to 2.5Gbps. Have a good one.

@BennySoh Hi, did you go ahead with change?
If so, was it easy to do?

I may be doing the same in a few months time.

Hello, Yes, Ive gone on to reassign WAN to igc3 which is 2.5Gbs. It was a seamless Interface reassignment as mentioned by SteveITS.
