@shdf, thanks... i've accidentally moved /etc to /home but that was easy to see.
I'm wondering if there is no file/folder move history feature in WinSCP ? Maybe im just blind...
@bilbokitz, Sure no problem, but keep in mind that my ISP requires vlan tag 835 (for pppoe) and my modem IP is: 192.168.254.254
Let's first start in normal router mode and without any config part...
First of all I've disabled everything that I do not need or use (Wifi, Mobile aso.) and then changed the default ip and did a Reboot, just in case.
After the restart I've activated bridge mode (modem will reboot) and set my VLAN tag under Broadband >> Internet Channel.
Don't forget that the LAN cable goes from any yellow ethernet port (not the red one!) into the WAN port of your main Router...
I think that you will probably don't need it but here is the important part of my /etc/config/network (the rest should be default):
config device 'wanptm0'
option type '8021q'
option name 'wanptm0'
option macaddr '10:13:31:xx:xx:xx'
option ifname 'ptm0'
option ipv6 '0'
option vid '835'
config config 'config'
option wan_mode 'bridge'
config interface 'lan'
option type 'bridge'
option proto 'static'
option netmask '255.255.255.0'
option ip6assign '64'
option force_link '0'
option ipv6 '0'
option pppoerelay '<set by script>'
option ipaddr '192.168.254.254'
list ifname 'eth0'
list ifname 'eth1'
list ifname 'eth2'
list ifname 'eth3'
list ifname 'eth5'
list ifname 'wanptm0'
It should work, if not go reset the DGA and do a clean reconfigure.
I started with fw 1.0.2 and GUI 3.25 and didn't had any problems to set up bridge mode.
Now i'm on fw 1.0.3 and GUI 4.6, but i would try fw 1.0.3 + gui 3.25 first and if its working you can always upgrade the GUI later on.
Let me know how it went and if you have any questions just ask...
