I'd say your router (Router1) isn't doing NAT for packets from other
subnets than it's LAN interface is configured for -- regardless of the
(correctly) configured internal additional route.

So your option would be to set up PC1 for doing NAT, not necessarily
for packets 192.168.2/24<->192.168.1/24, but for all packets from
192.168.2/24 going to the internet.

Your provider most likely does not have anything to do with all this.
