Relay more than 1 server??

[radioman]

Hello

Is it possible to have more than 1 relay server? If so, how do you set it up? I am currently running 1 "main" DNAS server and a relay off this. Everything works well. But when I try to relay a 2nd relay - the Ads do not trigger on the relay servers... I have tried the following:

Main -> Relay -> Relay

and

Relay<- Main -> Relay

Hope that makes sense? But on both setups the relay adverts do not trigger. If I use only 1 relay the adverts work fine.

Any ideas please?

Thanks
