VPN: left subnet equals to right subnet in IPsec configuration
Actually NethServer don't support site to site IPsec VPNs, but if somebody create an account specifying a remote network this network is added in the ipsec.conf as left and right subnet.
Probably that configuration doesn't have to be added to ipsec.conf until nethserver will start support site to site IPsec vpn, after that the left and right subnets have to be different, of course.

In a host to net configuration probably it doesn't cause problems, but probably is not the correct configuration.
In a "site to site" configuration (still not supported by web interface) this behavior should be a bug because remote and local network (left and right subnets) have to be different.
Trying to make an IPsec manually (e.g. from console) would be more difficult.
In any case it doesn't seem to be a correct configuration.
