Had A Question on IGMP Proxy and pimd

I had a question in the comments on the firewall rules and IGMP Proxy and pimd based upon the post DLNA: pfSense and IGMP Proxy – nope, use pimd. Unfortunately, I deleted that comment when cleaning out the spam (imagine that – a real comment!). To the commenter: Sorry ’bout that!

Anyway, when I was working on that issue, I had any-any rules in place between the server subnet and and client subnets. Since then, I have put my FreeNAS server in place with separate physical NICs (with VLANs coming – I’ll post on that) so the need to proxy IGMP is no longer an issue.

However, based upon some Google University research, I expect that you would need the following rules between your networks:

  • IGMP
  • port 5001 rule (TCP/UDP)
  • Port 2869 rule (TCP); used for DLNA / uPNP discovery (SSDP)
  • Port 1900 rule (UDP); used for DLNA / uPNP discovery (SSDP)

About Mike Pelley

Let’s see… A little about me… I’ve been around information technology since 1983 with computers such as DEC Rainbows (weird machine – the standard DOS couldn’t format its own floppy disks – remember them? – and I had to format them on a friend’s IBM PC) to Radio Shack TRS-80 to Apple ][e and Apple //c in the beginning. I have programmed in 8-bit assembly language on 6502, FORTRAN and COBOL on IBM System/370 (and I still hate JCL), VAX BASIC and COBOL (and a weird and massive WordPerfect 4.0 macro) on DEC VMS (Alpha), C/C++ on Digital Unix (ALPHA), and C/C++, Perl (it may be powerful but I still hate it), PHP on Linux (Red Hat, Centos, Ubuntu, etc.). I have work with databases such as Digital RDB (later to become Oracle RDB), Oracle DBMS, Microsoft SQL Server, MySQL and PostgreSQL on VAX, Alpha, Sun and Intel. Check out my professional profile and connect with me on LinkedIn. See http://lnkd.in/nhTRZe I still think that Digital created some of the best ideas in the world: VAX clustering, DSSI disks (forerunner to SCSI) and the Alpha processor (first commercial 64-bit processor – Red Hat screamed on an Alpha!). DEC just could not seem to be able to give air conditioners away to someone lost in the Sahara Desert! VMware is one of the best ways to get the most out of an x64 server. And I have tried Oracle VM, Virtual Box and Microsoft Virtual Server. Outside of that I am a huge military history buff starting in the early 20th century. I love Ford Mustangs (my ’87 Mustang GT was awesome) and if I had the money I would have a Porsche 928S4. If I had a lot of money I would have a Porsche 911 Turbo. I also play too much AmrA 3 Exile mod. Over 5,000+ hours... I have a wonderful son, Cameron. I have a long suffering (Do you really need all that computer junk?) wife, Paula. I live in Paradise, Newfoundland and Labrador.
