I'm having trouble configuring my Fritzbox 7530 as a router only behind my ISP modem, I configured the modem in bridge mode on VLAN 158 as required by my ISP. But I'm confused how to configure OpenWrt, so far I think that I can't use the DSL port but instead use one of the LAN ports as the new WAN right?
Another complication is that my ISP is expecting a specific mac address (the modem's) and now I'm not sure if that configuration should also be on the OpenWrt router or not?
This is my current config for the Fritzbox 7530 that runs as modem+router.
config interface 'loopback'
option device 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config globals 'globals'
option ula_prefix 'fdaa:9599:affc::/48'
config dsl 'dsl'
option annex 'j'
option ds_snr_offset '0'
config device
option name 'br-lan'
option type 'bridge'
list ports 'lan1'
list ports 'lan2'
list ports 'lan3'
list ports 'lan4'
config interface 'lan'
option device 'br-lan'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
option ip6assign '60'
config device
option name 'dsl0'
option macaddr '<MAC>'
config device
option name 'dsl0.158'
option ifname 'dsl0'
option type '8021q'
option vid '158'
config interface 'wan'
option device 'dsl0.158'
option proto 'pppoe'
option username '<USERNAME>'
option pppd_options 'debug'
option password '<PASSWORD>'
option ipv6 '0'
config interface 'wan6'
option device '@wan'
option proto 'dhcpv6'
config interface 'tailscale'
option proto 'none'
option device 'tailscale0'
A minor detail is that I'm trying a bridged configuration because the dsl line has micro cuts I think and for some reason the Fritzbox cannot reconnect successfully without a reboot (or removing the vrx518 kernel module and modprobing it again which is annoying and crashes the router sometimes)
It's somewhat similar to this issue but it's a different router: BT HomeHub 5A not reconnecting when re-plugging DSL cable - #19 by takimata
The last kernel log I find after the DSL is down and it can't reconnect is:
[46448.439233] vrx518_tc:ptm_showtime_exit: Line[0]: show time exit!
This looks like a different issue, because it sounds like the connection works fine at least initially in this case. On a device which needs that hack it wouldn't work at all (on affected devices, the DSL link can be established, but no data is transmitted over it).
@janh You are right, that patch is for different 7530 versions that always fail to connect with vrx518 0000:01:00.0: dc_ep_clk_on failed. The connection on my 7530 works fine until it cuts off for a few seconds and it has to reinitialize.
I tried the following config and it didn't work, so at this point I'm pretty sure it's the a modem problem and not OpenWrt's. The modem's UI is extremely simplistic so I don't really have much options to try (I wish it was OpenWrt compatible):
everyone!
