    Can no longer access modem from behind router - VLAN question

    I'm trying to think through this in my head. It worked before there was any VLAN tagging. Then I had to add VID 101 to 'Internet' traffic for the VDSL. This is what broke it. So apparently the modem can't 'understand' tagged traffic that is destined for it? Is there some sort of way to exclude...

    Can no longer access modem from behind router - VLAN question

    How can I remove the NAT and Firewall rules without rebooting? I am doing some more testing but my knowledge of Linux command/switches is atrocious.

    Can no longer access modem from behind router - VLAN question

    So even when I ping 192.168.254.254 from the router I get 20ms responses.

    Can no longer access modem from behind router - VLAN question

    I did "ifconfig br0:0 down" and the pings stopped. Then I did "ifconfig bri0:1 192.168.254.253 netmask 255.255.255.0" and it started replying again, but at 25ms...?!

    Can no longer access modem from behind router - VLAN question

    And while I can ping it, I still can't access it via a browser. A tracert looks normal - first hop is the router and second hop is the modem.

    Can no longer access modem from behind router - VLAN question

    It started pinging for a while before I made any other changes (like out of nowhere). I have three ping -t running. One to the router (less than 1ms). One to 8.8.8.8 (17-18ms). One to 192.168.254.254. Previously it was less than 1ms. Now it is replying around 24-26ms?! Then it will miss a...

    Can no longer access modem from behind router - VLAN question

    Yes. If I static a device on the 192.168.254.0/24 network and connect directly to the modem, I can access it even when it's in bridge mode.

    Can no longer access modem from behind router - VLAN question

    I added the following command "iptables -t nat -I POSTROUTING -d 192.168.254.0/24 -j SNAT --to 192.168.254.253". It looks to have applied without any errors, but I still can't access the modem.

    Can no longer access modem from behind router - VLAN question

    I believe it does have a true bridge mode now (called Transparent Bridging). In the earlier firmwares, it didn't exist and you had to use DMZ Pass Through. A PC behind the router can ping 192.168.254.253 (the subinterface on the router). I will test NAT.

    Can no longer access modem from behind router - VLAN question

    I have connected a cable from Port 2 on the modem to Port 8 on the router. I ran the command "ifconfig bri0:0 192.168.254.253 netmask 255.255.255.0". The router can ping 192.168.254.253 and 192.168.254.254. However, a client behind the router can't ping/access 192.168.254.254. I also tried...

    Can no longer access modem from behind router - VLAN question

    This is the exact same modem (Arris NVG448BQ). With ADSL2+, I used "ifconfig eth0:0 192.168.254.253 netmask 255.255.255.0" and could access the modem from behind the router. When I upgraded to VDSL2, I initially couldn't get PPPoE (bridge mode) working on the router. After some research, I...

    Can no longer access modem from behind router - VLAN question

    ISP Modem - Arris NVG448BQ Router - ASUS GT-AC5300 This setup is running in bridge mode. Previously, I had ADSL2+ and was able to access the Arris modem from behind the ASUS router by entering this command: ifconfig eth0:0 192.168.254.253 netmask 255.255.255.0 It created a subinterface for...

    ASUS GT-AC5300 won't connect to WAN after DSL upgrade from ADSL2+ to VDSL2

    I got it working. VDSL2 requires VLAN tagging. I had to set the WAN VID to 101 for my ISP (Frontier).

    ASUS GT-AC5300 won't connect to WAN after DSL upgrade from ADSL2+ to VDSL2

    I have it set to 1492. That's what it was on for ADSL2+. That's also the value the ISP modem gets when it's set to Auto. The workaround for now is using DMZ/IP-Passthrough to my router.

    ASUS GT-AC5300 won't connect to WAN after DSL upgrade from ADSL2+ to VDSL2

    Router - ASUS GT-AC5300 ISP - Frontier ISP Gateway - Arris NVG448BQ (Transparent Bridging) Service Type - VDSL2 PPPoE PAP I just had my service upgraded from ADSL2+ to VDSL2. When using the Frontier provided gateway as a router, everything works fine. However, when I put it in bridge mode and...
