Does anyone know how to set the VPI and VCI?
What device is this for? I’m not aware of any ATM support in Mikrotik.
(doesn’t mean there isn’t any…)
I have ISP that provide IPTV and VOD service. They came with a tp-link modem router and an hd box (the tp-link has atm vci vpi parameter).
If I config the tp-link as a bridge and the mikrotik as the router, internet work fine and the VOD also but the IPTV has no luck. Do you have any advice?
You probably need to configure your router to do IGMP proxy.
It is in the “routing” menu (not IP > Routes) and if you do not see IGMP proxy as an option there, then you need to install the multicast package.
I have set the IGMP but still no luck, both the two interface show active but no packet activity.
It would be useful to know how the modem bridges the various ATM VCs onto the Ethernet interface - does it map them to VLANs or does it just have some sort of pattern matching which decides that traffic X should go onto VC x, while traffic Y should go onto VC Y?
If VLANs, then all you would need to do is create a vlan sub-interface on the ethernet interface where the modem is connected, and figure out what IP address needs to be used on that vlan, and then use IGMP proxy with that vlan as the WAN.
Thank you. I got it worked perfectly. By the way, what firewall rules should I set?
A typical chain for input is one which allows established,related connections, allows ICMP, allows in-interface=lan, and drops everything else.
A typical chain for forward is one which does fast-track on established,related connections, then allows established,related connections (some connections don’t support fasttrack, so you need an allow rule as well), then allows out-interface=wan, and finally drops everything else.
You would probably want to add a rule to accept dst-address-type=multicast in-interface=IGMP WAN INTERFACE (not sure what your working solution required you to change)
