I've ben playing with computers a long time, but I've never had the chance to play with some switches until today. I've been with my current company for 2 months and am learning their network configuration by being thrown into the deep end. Let me explain what I have then what I need to do and we go from there.
There are 2 office locations (down the street from each other). They have different operations and were set up with different IP address tables (DHCP handled by a server). We'll call location 1 "Home" and location 2 "Remote". Home has a dedicated internet access (DIA). That comes into a SonicWall Firewall (managed by ISP). It then goes into a HP 2920 that passes it along to the everyone in the building and the servers. There is a pipeline (EPL) that also is connected here that leads to Remote. Remote has an HP 2920 but no DIA. All internet traffic at Remote has been routing through the EPL to Home. Home uses 192.168.1.x. Remote uses 192.168.9.x. The EPL VLAN uses 172.x.x.x. As it is currently built (configured by an expensive 3rd party). Now, management has decided that Remote needs it's own DIA so we don't rely on the pipe for the internet access but only for the VLAN (access the DNS and other servers at Home). They've also decided that we need to use a SonicWall for security at Remote. Our ISP has turned up a new port on their box and we've been given a range of IP addresses. I've connected a computer to the sonicwall and connected the sonicwall to the ISP and everything works dandy.
However, I cannot figure out how to get the HP 2920 to allow internet traffic through the sonicwall and traffic to Home through the VLAN. I'm very new to networking, so any help would be greatly appreciated. I'm assuming that the default gateway would need to be updated to represent the sonic wall's IP address, but whenever I try to change it via the web portal, it reverts back. I've found my way into a console connection, but the menu under console doesn't give an option for the default gateway.
I'm very new to networking and any assistance would be GREATLY appreciated. We're a Non-Profit organization, so we'd rather not have to pay big bucks for the expensive 3rd party to come in to do this.
