This post is intended as a simple guide to enabling "bridge" mode on your Sagemcom F@ST 2864 modem.
This is a proper bridge mode, rather than simply PPPoE forwarding. You will get the full speed of your connection with this setup. This guide is for VDSL only. Settings for FTTH can be found here: http://www.dslreports.com/forum/r28198627-
***VERY IMPORTANT NOTICE***
This process and any changes of your Sagemcom modem settings are absolutely not supported by anyone. Neither Teksavvy or Bell will help you with issues that arise due to changing settings on your modem to an unsupported configuration. If you follow this guide you do so entirely at your own risk.
Before we begin I'd like to thank forum user sibisties for his excellent work on the Sagemcom 2864 stats and unlock tool. Without the unlock tool this process would be a great deal more complicated. And thanks to everyone else on the forums who helped with various firmware files and testing ideas.
As of this posting the tools and settings used are known to work on the following firmware versions:
FAST2864_v6740S
FAST2864_v66396
You can check your modem's firmware version in the About page on the Connection Hub site (e.g. http://192.168.2.1/index.cgi?page=about )
Now for the guide:
1) Download sibisties' Line Stats & Telnet Unlock Tool from here: https://mega.co.nz/#!ohMxkArD!JKqV9gd9wBZBRIe_EFPwt0HFqalrdv9fVx72qQqm38A
- For more information on the tool and its features see sibisties' thread here: http://www.dslreports.com/forum/r28188441-Line-Stats-Telnet-Unlock-Tool-for-Sagemcom-2864-V1.01-
2) Connect your PC directly to the Sagemcom modem and run the unlock tool, select the "Telnet enable" option and enter the requested information.
3) Run telnet.exe or any telnet connection program you have to connect to the modem at 192.168.2.1, log in with user: admin, pass: admin
3.5) Run the following commands at the Homegateway> prompt:
conf set /dev/br0/enslaved/eth2.35/stp 0conf set /dev/br0/enslaved/eth2.35/def_vlan 1conf set /dev/br0/enslaved/eth2.35/vid 1conf set /dev/br0/enslaved/eth2.35/tagged 0conf del /dev/ppp0conf del /dev/ppp1conf del /dev/ppp2conf set /dev/br0/dhcps/enabled 0conf set /fastpath/enabled 0conf set /dev/br1/enabled 0conf set /fw/enabled 0conf ram_set /dev/br1/volatile_enabled 0conf reconf 1system rebootYou should see Returned 0 after entering each command, this means that the command was accepted without errors.
**If for some reason your modem does not reboot after entering the last line, REBOOT YOUR MODEM**
4) Once the modem is finished rebooting, connect your router's WAN port to any one of the modem's LAN ports. Then configure your router's WAN for PPPoE using your DSL login credentials.
4.5)If you have a router running a WRT or Tomato firmware you can use the following commands (on your router) to allow you to access the modem's config page from behind your router*:
ifconfig `nvram get wan_ifname`:0 192.168.2.2 netmask 255.255.255.0iptables -t nat -I POSTROUTING -o `nvram get wan_ifname` -j MASQUERADE*Do not use this setting if your internal network uses the 192.168.2.X range.
Otherwise you can connect your PC directly to the Sagemcom modem, assign it a static IP of 192.168.2.2 and access the modem's configuration page at http://192.168.2.1. Telnet access will also work.
Other notes:
a) This process is not compatible with IPTV due to the connection requirements of Bell's IPTV service. Do not use this if you have IPTV service as it will disable it.
b) Your modem cannot connect to Bell's ACS management system when in bridge mode. This means that you cannot receive firmware updates or direct support from Bell for connection issues. In order to receive firmware updates you will have to factory reset your router to defaults. It is possible to update the router's firmware through telnet when bridge mode is enabled but that process is not covered by this guide.
c) The settings in the guide are persistent even if your modem is rebooted/loses power. If you need to remove the settings you will need to reset your router to factory defaults. This can be done by holding the reset button (on the bottom of the modem) for ~30 seconds until you see the power light (top LED) go out, then release the reset button. The modem will reboot with all settings at their factory default values (as shipped by Bell).
