You need to add a route to 192.168.1.0/24 subnet on the gateway device in 172.22.1.0/24 pointing to the f0/0 interface of 2611.
When you ping the production network from the router, the source IP address of the PING will be the interface IP from f0/0 which is of same network and will get reply and when you try from your server (lab network) the source ip address will be from 192.168.1.0 subnet and the production router will not have a route to 192.168.x.x subnet.
So add a route in the production network gateway device and it will work.
