Hi,

1) The Company uses the SonicWall NSA 4500 for the Firewall
2) This company uses the network: 192.168.61.0/24
3) The IP Address of the above SonicWall is 192.168.61.12
4) But the IP address of the Gateway is 192.168.61.1
5) My question: i) Which Device is the Gateway (that has the IP of 192.168.61.1)?, ii) Is the Firewall (the above SonicWall) not a Gateway?
6) Explain it a little bit more details if you could please
7) Thanks

Question - what is the device at 192.168.61.1

The Sonicwall could be configured in a passthrough mode that doesn't have it acting as a gateway.

I would think that the LAN side of the Sonic is the .12 and the .1 is the gateway on the WAN side, no?

It sounds like you're getting confused as to what "gateway" means. In simple terms it just means the next route or hop a packet should take to go anywhere outside of its own network. So in the case of the Soncwall, its gateway is 192.168.61.1, which is probably your ISP's router, but to your internal network clients their gateway would be the Sonicwall.

Yeah, Vanbarsoun is most likely correct  If the Sonic was acting as the gateway and the ISP modem/router is just a passthrough then the Sonic IP would be the gateway.

you havnt mentioned if you have a server and the server handles routing then your server could be the gateway and that send out packets to your isp via your sonicwall

The default gateway is the endpoint of your network.

Typically this is a router, unless your firewall appliance is directly connected to the network, then it most likely has a second NIC that would be pointing outsite of the network...this would typically not have the same IP address as your internal network.

Basic configuration would be:
PC - Firewall - Router - WWW
