Hi all,
I have been attempting to configure mangle on one of your router boxes using version 2.9.18 firmware. I am attempting to change the TTL of incoming UDP and IGMP packets so as to stop the packets propagating over other links on the network.
The packets are coming from remote CCTV cameras to a central site so I need to change the TTL so that the packets will only stay on the central site and not be sent over the other links we are using.
We are using a bridge configuration with nstreme and wds enabled, the routers at both ends of the link are using 2.9.18
So really just looking for the correct command to enter. 
Thanks in advance.
