QuoteI can confirm you the same problems with 5C0 on my VMG8924. Port forwarding is reset after reboot but also after a disconnect/reconnection of the WAN port (in my case a DSL PPPoE).I think Ronski had exactly that same issue. Zyxel gave him a link for V100AAKL6b1.bin which has hopefully cured it. The only thing is they pulled the link soon after, so its a good job he kindly shared the link and I was able to get a copy before they deleted it.. I dont know why they are so hesitant about leaving up the more recent firmwares :/

Have you tried it?
zyxel are acting a bit odd using dropbox for files, and hidden links.
Note: These firmware cannot be flashed to the Eircom F1000 banded version of this device from the web interface, an "invalid model id" error occurs.
