My ISP forces us to use their modem/router. The provided modem/router is a custom NETGEAR VEGN2610 Telco gateway.
I want to manage my LAN, WiFi & QoS using my previous modem/router: a D-Link DVA-2800.
I can establish an internet connection from my ISP with the D-Link but they refuse to disclose SIP registration details, so I can't have VoIP for my home phone unless I stick to using the ISP modem/router.
I'm thinking of trying this set up... but I have questions -- particularly about NAT, DNS and Port Forwarding.
on ISP modem/router:
- WAN IP, Subnet & Gateway: auto from ISP
- DNS: Auto? 1.1.1.1?
- NAT: Yes? No?
- LAN IP: 192.168.0.1 (255.255.255.0)
- DHCP Start IP: 192.168.0.2
- Reserve: 192.168.0.2 for DLINK
- Port Forward: 443 & 80 to DLINK? (for my WEB SERVER)
- Disable: WiFi broadcast/radios
on DLINK modem/router:
- WAN IP: 192.168.0.2
- Subnet: 255.255.255.0
- Gateway: 192.168.0.1
- DNS: Auto? 1.1.1.1?
- NAT: Yes? No?
- LAN IP: 192.168.1.1 (255.255.255.0)
- DHCP Start IP: 192.168.1.2
- Reserve: all my usual home devices.
- Port Forward: 443 & 80 to MEDIA SERVER?
- Enable: WiFi broadcast/radios
connect: Ethernet cable from a ISP LAN port to the WAN port on DLINK.
Would this work?
Will double-NAT be an issue? Should I just expose the DLINK to all ports by setting it as a DMZ server on the ISP modem/router? How is double-NAT not an issue then? Where do I specify my preferred DNS servers?
The ISP's custom firmware version of the NETGEAR gateway is really restrictive, and the WiFi radios are not very good. I would very much like to manage the LAN and WLAN with the D-Link modem/router.
Any help would be appreciated, thanks!
