How to connect my class B network to a Class C subnet

[Onyxtacular]

I have 5 vlans set on my LAN

10.1.x.x - 10.5.x.x  They connect to an ASA-5505 which is connected to my t-1

Recently I purchase a dual wan RV042 to utilize connecting on just purchased DSL (3mb/5 WAN1) and SAT (15MB/3 WAN2).

Under the Setup-Network_LAN Settings

is Device IP Address: 192.168.1.1

Subnet Mask:  255.255.255.0

255.255.255.128

255.255.255.192

255.255.255.224

255.255.255.240

255.255.255.248

255.255.255.252

Then it lists my subnets

How do I set this LAN subnet's or 255.255.0.0   to match these?  My ip are all over the place based on location of device, etc.  

Do I have to restructure my entire network to accommodate the rv042?

Thanks

Have you tried telnetting into the device and configure a subnet plus mask that way?

The web GUI might be limited to preset options

I didn't see anything in the manual about a cli.  I'll give telnet a try.

Thanks

Let me know how you go

Hi Dennis,

Turns out I have the newer version where Cisco gutted the cli :(

Hi,

Your question is not clear. Please provide full Subnet and IP address schemes, so I can found the right solution for you.

Hi,

As practical, it is not possible to connect your subnet without routing. It is advisable that you should use static or dynamic routing for your networks. 

So please configure routing.
