How to effectively "bridge" the Sagemcom 3864v3 CABLE router

vsolanki

ISSUE RESOLVED: How to effectively "bridge" the Sagemcom to allow use of your usual router.

 

If you still want to keep the Sagemcom 3864 v3 router connected because your better MAIN router does not work when connected directly to the cable modem then using DMZ works as a alternative to bridging. (Bridging is not available in the sagemcom 3864 v3 menus)

 

I am getting full speed by wifi 95-100mbs, port forwarding works, dyndns works:

 

On SG3864

1. Set any static ip address eg 192.168.0.1

2. Goto advanced setup, NAT, DMZ host

3. Set DMZ host to any ip address (This will be used in the background on your main router) eg 192.168.0.138

4. Do NOT set any port forwarding or triggering etc on the SG3864

5. Enable dyndns

 

On your MAIN router

1. Connect ethernet cable from one of the four LAN ports of SG3864 to the MAIN router internet port

2. In the Internet setup: set same static IP above eg 192.168.0.138, gateway 192.168.0.1, dns 192.168.0.1

3. In the LAN setup: Set the static IP to your usual subnet eg 192.168.3.138

4. Enable DHCP and wifi

5. Set any port forwarding, triggers etc on your MAIN router (NOT the SG3864 otherwise will not send to your main router)

 

Back on SG3864

1. Switch off DHCP

2. Switch off wireless with the button on the back

 

I am getting full speed by wifi 95-100mbs, port forwarding works, dyndns works.

 

Good luck!

So what you've done is set up 'Double NAT'.

 

If you are on Optus HFC cable, you don't have to use the SagemCom.
