Ok, site to site, PFsense on both ends, forget the iroute. I don't see a route to the 192.168.10.x/24 network on your server…. that's why you can't get to the client-side. Although, I do see a route to the 192.168.194.0/24 network.... which looks like the LAN on the client-side.... are you sure the client is on the 192.168.10.0/24 network? Might want to double check... cause it doesn't look like it.
Post your server1.conf and client1.conf.
On the client-side, it looks like you're double NATing, so you'll have to either remove it or keep your static route in place (someone correct me if I'm wrong)
