AlexFullmoon Posted January 6, 2022 Share #1 Posted January 6, 2022 I'm running latest 6.2.3 which again has support for onboard NIC, with MAC addr 38:XXX (as seen in BIOS). I also have Intel EXPi9301CT with MAC addr 68:XXX (as written on it). When I plug external along with onboard and put both in grub.cfg, i.e. set mac1=38... set mac2=68... I can boot, both NICs work, but MAC addresses apparently swap around, i.e. internal NIC takes 68:XXX address and external 38:XXX. With external plugged and set mac1=68... only external NIC works, and it uses its own 68:XXX MAC address. With external plugged and set mac1=38... again only external NIC works, and it uses 38:XXX address. When I leave only internal NIC, nothing works. What might e the cause and what I am to do? I guess I can keep external NIC and leave it unused, but I'd rather use it in another project. UPD: I suspect that internal NIC drivers don't work in recovery mode which happens after any changes in grub.cfg. UPD2: External NIC always becomes #1, and internal #2, which might explain why setting only one NIC in config doesn't work. Is there any way to reorder them?

pocopico Posted January 6, 2022 Share #2 Posted January 6, 2022 The idea behind setting MAC address in GRUB, is to set the Mac addresses to synology Mac addresses and not to match your Mac addresses. Try to either leaving these variables empty or to set a Synology generated MAC address. Quote Link to comment Share on other sites More sharing options...

Any point to get real Synology MACs outside of QuickConnect and such? Quote Link to comment Share on other sites More sharing options...
pocopico Posted January 6, 2022 Share #4 Posted January 6, 2022 I’m not very sure if this is required for all applications but I’m sure that the ability to fake the MAC address to a synology one is there for a good reason. Quote Link to comment Share on other sites More sharing options...

Anyhow, I now use Redpill, and it plays nice with internal NIC (and tg3 driver). Quote Link to comment Share on other sites More sharing options...

AlexFullmoon Posted June 10, 2022 Author Share #8 Posted June 10, 2022 Oh, right. It was a minor problem with managing network addresses on router, and in DSM UI - stats widget defaults to eth0. Larger problem was that internal nic worked only when external is plugged in. Redpill/7.1 for me is just as stable. The only problem I've had is DSM7 doesn't support my UPS anymore, had to poug it into RPi and share over network. 1 Quote Link to comment Share on other sites More sharing options...
