PPPoE MTU > 1492

My routers and radios support up to 1520 MTU on their interfaces. Can I then run 1500Byte pppoe sessions with no problems?

I have tried it with cust CPE (nano M5) set at 1500 MTU/MRU and pppoe server at 1500 and it still connects at 1492.

I can’t use MRRU with the M5 radios unfortunately.

Curious if anyone else has tried this.

Thanks
