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

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.

Does this work the same with the Sagemcom F@st 5366 TN modem? I want to use my Billion VDOX 7800 as my wifi distributor.

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

If you're on OptusNet Cable, you can just attach your [insert brand here] Router to the CM500V Cable modem and use it.  As the CM500V is a modem only, it performs no routing and just passes the external IP via the WAN port.

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

How do i make the spare one into a bridge router so i can link my smart tv to the main router wirelessly 

I am not a complete novice but not that tech savvy

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

thanks - i think that i have sorted out the bridge router settings but i am having difficulty with the instructions with the main router 

iten 1 under on your MAIN router -  what plug on the main router do you use to connect the cable from one of the 4 LAN ports of the SG3864?

item 2 - isn't the static address 192.168.0.1 and not 192.168.0.138?
