Hi All,
I'm new with PfSense and I need your help  :)
I cant' find a reply in post like that in all forum.
I have two Fortigate and want to sustitute with PfSense.

My configuration is :

office 1 - 
lan:        192.168.300.x/24
wan1:    static ip address 123.123.123.123
wan2:    static ip address 124.124.124.124

office 2 -
lan:        192.168.600.x/24
wan1:    static ip address 125.125.125.125
wan2:    static ip address 125.125.125.125

is it possible to create a IPSEC VPN between the two site having load balancing in both offices ?
I immagine a need to create a vpn like that:

office1 wan1 -> office2 wan1
office1 wan1 -> office2 wan2
office1 wan2 -> office2 wan1
office1 wan2 -> office2 wan2

and

office2 wan1 -> office1 wan1
office2 wan1 -> office1 wan2
office2 wan2 -> office1 wan1
office2 wan2 -> office1 wan2

is it possible to use dynamic ips ?
For this configuration what kind of hw do you recommend ?

Both office has Windows and iOs infrastructure, it could be a problem ?

Thanks

Dany
