BGW320-500 in front of firewall
I do NOT have any external IPs. I do have my own internal DHCP.
I was able to put the BGW320-500 in Passthrough and that is all good. Everything works fine.
However, the only way this works is if the WAN side of my firewall pulls internal DHCP from the BGW320-500.
Is there no way, to have the BGW320-500 internal DHCP disabled and still have my firewall pull the external from the BGW320-500 modem?
I have configured it, however, with the BGW320-500 internal DHCP disabled this is what happens:
My firewall will pull an external ATT IP.
Everything will work for a bit, then when the firewall renews it pulls zero IP and everything goes down.
I then have to plug my laptop into the modem and re-enable DHCP so the firewall will pull an internal IP from the BGW320-500
Just out of security I don't want some to plug into the modem and get on the internet. Of course, they won't be able to reach my LAN. It's just the fact of it at this point.
