Help with initial setup
I have an existing local SOHO system, which connects to a local campus network.
My incoming link from the next level switch, behind two levels of firewalls, comes into my house on a static IP 192.168.10.xx/24 link which comes into an HP 16-port switch for local distribution. I get DHCP from a server at some higher level. I get DNS from another external server with a 10.10.10.xxx address.
I am going to move to a separate VLan above the two firewalls, and thus need to insert my own. I have a WG-T20 for this and am trying to set it up. I put it between the incoming link and the HP switch, and tried to do setup, and when it fails I just disconnect it and remove it from the link.
I went through the basic UI setup process but have some problems. Notably that all my local systems with 192.168.10.xx DHCP addresses from my current higher level server fail, unless they are also going through my WiFi (Netgear) router, which has grabbed a 10.0.1.xx DHCP address from the T20.
I setup my interfaces so that I use an existing static IP on the external (incoming) link (port #1) and set it to the current gateway on that external segment.
And then the local port (#2) would do DHCP and feed into my local HP switch which feeds all other local connections. I point to the existing gateway which I get from DHCP (192.168…..).
I then tried to set the IP of the Trusted port (local, #2) to 192.168.10.1, and the DHCP range to .2-.254 since that is what I had before (& now), but the T20 gives an error, since “this address is in the same range as the external interface IP”.
I thought that these would be two different partitioned address spaces.
I could leave the Trusted (internal, local) range to the default 10.0.1.xxx range, but that would mean changing all of my local addresses. Since they are all DHCP that might be automatic, but some also have the 192. Gateway configured in and that would have to be changed.
Later I want to add a local DMZ and NAT two local externally accessible servers.
?? Any advice or guidance appreciated.
(I filed a support case with WG, but after 3 days, no response. :-( )
