iptables command for changing TTL

I am trying to use iptable to change outbound WAN TTL to 65 and can't get it to work.  Here is the command I am placing in the firewall.

 

iptables -t mangle -A POSTROUTING -o eth0 -j TTL --ttl-set 65

 

I've tried other ports as well, doesn't seem to change anything.
