Stangri recommends if not requires nfttables for the most recent version of his PBR & I’m inclined to err on the side of caution when it comes to potential leaks. GL still uses iptables even on the OWRT 23.05 based Flint v2. @admon confirmed that little potential ‘gotcha’ a lil’while ago.
Yeah, it’s pretty stupid simple. For best results use the U-boot Debrick Method (see GL Docs, attached). You could simply flash using LuCI’s Sysupgrade function but you’ll defiantly have cruft & probably wasted space fr leftover GL binaries. I just finished helping another OP over in Iran flash their Flint v2 w/ OpenWrt 23.05 SNAPSHOT r24909-65f599223d using Sysupgrade. 23.05 works but again… mind the cruft.
Don’t use the Sysupgrade tarball with U-boot; that’s just gonna be a bad time. There’s a U-boot specific image.
You will be dumping the closed source SDK that GL uses so yeah, you may well hit a pref decrease… but on the other hand I read a report on this forum that a flashed Beryl AX, 300 Mbps WG GL advertised max was breaking ~500 Mbps WG… so who knows? You can always revert to GL by U-boot.
Full disclosure: my OWRT 23.05’s PBR is on a junker that can’t even break 110 Mbps down over WG. I use it as a jumpbox. The ER-X really isn’t a great device these days. My Slate AX acts as a WG gateway for everything else.
As all things in life, caveats apply. See related thread:
