Disable switch mode at 750GL

Mon Apr 13, 2015 8:33 pm

Hi, I have a 750GL with 5 ethernet ports:

1- ISP A ( static IP )
2- ISP B (dhcp)
3- LAN_DMZ ( IPs: 10.10.0.1/16 and 192.168.3.1/24 )
4- ether4 ( empty)
5- ether5 (empty)


I am listening a dhcp server on ether3 (more specific at 10.10.0.0/16 address ). But the dhcp server from the ISP B (ether2) is delivering some address on ether3 .

How do i disable or isolate ether2 ?

thanks

2 DHCP servers come handy when you separate them completely. But If you connect all 3 Ethers to one switch or hub it made some problem like this.
There is no need to disable Ether2. Just disable the DHCP server you don't wanna make dynamic address.

For example in my 450G I did this:
Ether1: Hotspot + DHCP
Ether2: ISP1
Ether3: ISP2

My ISP 2 is dhcp. I cant disable it.

I guess I will block ISP B dhcp broadcast at LAN interface.

more suggestions?
