Is it possible to extend 2 different LANS across 1 WAN using 2 RV180's

[radiorick]

Trying to connect two locations together using a microwave link for the WAN.

Have an RV180 at each site.

Both sites have two LANS (192.168.1.x and 10.10.10.x)

Want to extend both LANs between the sites.

Can this be accomplished over a single WAN using 1 RV180 at each end and if so, how ?

Any help would be appreciated.

Do you have a VPN server?

No VPN server or funds to purchase one.

If this helps helps simplify any possible configuration please note that each LAN only needs to communicate with a single interface at the other site:

Site 1 Server on LAN #1 192.168.1.0 communicates with a backup server at Site 2. Backup server has multiple NICs and plan was to address one NIC on 192.168.1.0 to receive BU data from site 1.

Site 2 Server on LAN #2 10.10.10.0 communicates with a backup server at Site 1. Backup server has multiple NICs and plan was to address one NIC on 10.10.10.0 to receive BU data from site 2.

We have 2 rv180's and a point to point microwave link to work with.

Don't necessarily need to extend entire LANs and their associated broadcast traffic, etc. Only need to forward the server database backups between sites as described above.

Is there an advisable way to do this with the equipment we have on hand?

Thanks in advance for any help you can offer!
