Is it doing DNAT For the host 192.168.131.133 (converting it to 192.168.131.131? This doesn't make sense as 192.168.131.133 belongs to your internal network. > Chain POSTROUTING (policy ACCEPT) > num target prot opt source destination > 1 MASQUERADE all -- 192.168.131.131/24 0.0.0.0/0 192.168.131.131/24 is incorrect. If it's a particular host it should be 192.168.131.131/32 or simply 192.168.131.131. If it's for the network then it would be 192.168.131.0/24 (proper way to specify network). And again, just like Tim mentioned, you're not firewalling anything. At this point you're just basically routing & NATing.
