Sorry for taking so long @Ok-League-3645 and thanks again for the source link.

@johnson Thanks a lot for providing this

Could someone post the source link for VMG3925-B10B V5.13(AAVF.18)C0 ?

[johnson]

Sure, added to the same link.

thank you Johnson, does the below work for the B10C version as well ?

https://service-provider.zyxel.com/global/en/products/dsl-cpe/vdsl/modemresidential-gateways/vmg3925-b-series

also, on dropbox there are 3 files for the B10B, could I kindly ask for a laymans description of each of them, I think GPL.zip are the source files

3925-B10B-18-jumbo-statsV1.1.bin         7/6/2022 2:09 am
3925-B10B-18-jumbo.bin                         7/6/2022 2:09 am
VMG3925-B10B_V513AAVF18C0_GPL.zip   6/22/2022 5:27 am

and last thing, are the Zyxel 3925's in bridge mode ( modem passthrough / bridge mode ) still the best bet with VDSL lines, now that the "Baby Jumbo" fix has been implemented ?

thank you Johnson, does the below work for the B10C version as well ?

They appear to use the same firmware, this zyxel page lists the same firmware for both, and AAISPs wiki has:

The specification is very similar to the VMG3925-B10B that it replaces (in fact the same firmware is used on the B10B and B10C)

but I don't have a B10C to test.

also, on dropbox there are 3 files for the B10B, could I kindly ask for a laymans description of each of them, I think GPL.zip are the source files

3925-B10B-18-jumbo.bin - V18 firmware, just the patches for 1508 baby jumbo frames
3925-B10B-18-jumbo-statsV1.1.bin  - Same but including a small websever with easy access to line stats and a 48 hour log, screenshots and details here.
VMG3925-B10B_V513AAVF18C0_GPL.zip - Source package from zyxel.

and last thing, are the Zyxel 3925's in bridge mode ( modem passthrough / bridge mode ) still the best bet with VDSL lines, now that the "Baby Jumbo" fix has been implemented ?

Depends on your line! Second hand 8x24/3925 etc are cheap enough that they are always worth trying IMO.

super, thank you for that johnson - much appreciated 

the version I want is the included webserver one, to use with the VMG3925-B10C, so I can test this and report back, will be running in "Bridge Mode" with a Ubiquiti EdgeRouter X router ( ER-X)  behind it

"Modem stats server with logging and web interface -  a small mongoose based http server with simple visualisation of real time and logged statistics avaliable by default on modem-ip:8000 "

how do I remotely see the http server when I'm not on site, can I port forward to :8000 to see the Zyxel even when its in bridge mode, or does the Zyxel need one its ethernet switch ports ( LAN 1 ) to be plugged into the ER-X with a LAN ip of 192.168.1.1 for the :8000 to work ?

[johnson]

With the zyxel in bridge mode the PPPoE connection terminates on your router (the ERX), so accessing it remotely will require the same steps as exposing any other device on your network to the internet.

Lan access will require a second cable or the routing tricks to use one, and I would stop there. I wouldn't recommend exposing either the default interface or the stats server to the internet just as I wouldn't recommend exposing other devices on your network. I would look into VPN protocol like wireguard for secure remote access to a network.

I was able to set ptm0 and ptm0.1 MTU in modem settings to 1508 and it was showing MTU 1508 in ifconfig command.

but setting the MTU in ETH1 interface in openwrt didn't change the mtu for pppoe-wan interface it stayed 1492 and I also tried changing it manually but still was same 1492, tested via ping -f -l command.

Does anyone has an archive of mostly vmg4005 firmwares, but also similar? Its a simple bonding /modem/bridge and a nice piece for trying. Unfortunately zyxel ftp gone, and sources....just newest. Got few branded, will decide for jtag TP or nand reading. I hope under the nand is an SPI flash footprint...

do you think it would be possible to get that port 8000 mongoose server working on the VMG1312-T20B?
