Our Comcast Metro Ethernet service gives us an IP block, but I guess we only have one actual static IP address, and in order to use the block a static route needs to be set.
First question I have is can a ProCurve 5406zl L3 switch connect to the Comcast switch, basically I know I can set a static route on the switch, but will it accept a WAN connection?
Currently the Comcast switch is connected to our Sonicwall, but it uses the static IP address, so we only have the one public IP address available.
I would like to connect our L3 switch to the Comcast switch before it goes to the sonicwall, so I can have one line come from our L3 switch to the VoIP hosted service device without having to go through the sonicwall. If our L3 switch can be configured to use the IP block made available to us I could then use one public IP going to our sonicwall, and another IP to the hosted VoIP unit.
The only other requirements for a device to connect to the COmcast switch is that the port be configured as a trunk port, auto-negotiate turned off, set at 100M full
I think I can set a static route on the sonicwall and use the IP block, but I would rather not go through the sonicwall for the hosted VoIP appliance.
Second question is about which IP to use.
if we were given an IP block of
50.xxx.xxx.24/29
would I give the device that connects to the Comcast switch an IP address of
50.xxx.xxx.24
and set a static route that points to the gateway of our static IP address?
here is more information if needed.
static IP address given to us
50.xxx.xxx.20/30
gateway: 50.xxx.xxx.21
IP address: 50.xxx.xxx.22
IP block
50.xxx.xxx.24/29
usable range 50.xxx.xxx.25-----50.xxx.xxx.30
I've talked to Comcast support twice, one person told me to set a static route for the 50.xxx.xxx.24 address pointing to the gateway, another told me to set the static route for the 50.xxx.xxx.25 address. I also got 2 different answers for if our L3 switch could hook up to the Comcast switch, one said yes, one said no.
these guys are network engineers? I would just get another static IP address, but was told that would mean a change of service, and I really cant do that.
