Dual Pfsense, Dual WAN and IPSEC to separate local data?
This is probably a n00b question but would appreciate any advice if this is possible?
Currently we have Two sites, both with 2 static ip ADSL connections (4 in total).
We have a need for load balancing dual vpn connections between the sites. Due to very poor infrastructure in our area, we have very limited upspeeds.
I have determined it is not possible to load balance across dual OpenVPN connections at this stage (we also have a gateway issue where only one ovpn connection will stay up due to all connections being from the same isp and the upstream gateway being the same for all 4 adsl connections).
What I was thinking was setting up additional pfsense boxes at each site each managing a wan connection. Then setting up vpn connections between them. So 192.168.1.1 <–--> 192.168.2.1 and 192.168.1.2 <-----> 192.168.2.2.
Then manually setting the gateway on the servers which do file replication to the second gateway, and leaving all workstations on the first gateway.
Failover is not important here, the business size is very small, and its just about utilizing the the upstream as best possible. Currently as soon as the server does any tasks it saturates the link making all other tasks on the vpn unusable. Throtteling is not an option due to the very limited upstream as is.
Is this just a ridiculous network setup?
