Dreambox + Routerbord - Increases hop distance (ccam, gbox)

RouterOS General
1

Hello
In my home network, I recently replace a low budget ADSL Router for a Mikrotik RB951G-2HND. The RB connects to the internet via PPPoE on eth1, with a modem (D-Link DSL G624T) which is configured as bridge. The modem is completely transparent, so I cannot reach its IP across the network.
I managed to set everything right, and it has been operating flawlessly. However, I have a Dreambox connected to partners through the internet. In this connection, it is important the amount of hops between my Dreambox and the partners on the internet. After adopting this new solution (Mikrotik RB951G-2HND + D-Link DSL G624T), I notice that the distance between my Dreambox and my partners increased 1 hop, which disrupts the operation of the applications ccam and gbox (running on the Dreambox). The Dreambox is connected directly to the RB on eth2.

My questions are:
How to explain this increase on hops (distance)?
Is there some setting I can do to nullify their effect?

Thanks!
King

You could create a VPN or other tunnel between the two locations and reduce the hops. You could also use the mangle rules to rewrite the TTL on the packets which should “reset” the number of hops.

The following should change any packets that would only survive less then 100 hops to survive 254
/ip firewall mangle add chain=prerouting ttl=less-than:100 action=change-ttl new-ttl=set:254

If you go the route of changing the TTL then you may have to do this on both sides.

thanks for your reply. I’ll try the recommendations that you made, and then put the results here.
