Forgot to post this. I point you to what Harold recommended back when I first started. http://lists.netfilter.org/pipermail/netfilter-devel/2002-April/007420.h tml And other than google, it's been a while. How would I search for this? I tried google and came up with nothing. I'd like to look at this patch, although this would only solve the SIP problem right? Is RTP in there as well? Even if this did fix the problem it only fixes it for SIP programs, which may be all you care about. But like I said, the overhead of this on something like a 386 to do all that translation, especially when the ip address is never in the same place, that's a lot of text matching to do for something like a high speed video and voice conversation while running a remote assistance, or something of the like. UPnP is just another solution to the problem, that happens to solve a lot of other problems with clients that are UPnP aware at the same time. (And being a sysadmin myself, I must say a lot easier to set up than recompiling your kernel with these experimental helpers). But then I'm thinking of the users and myself on that one ;-) Cheers. -----Original Message----- From: netfilter-admin@lists.netfilter.org [mailto:netfilter-admin@lists.netfilter.org] On Behalf Of Kevin McConnell Sent: Tuesday, December 31, 2002 2:51 PM To: Roy Sigurd Karlsbakk; Glover George Cc: cuigl@ilion.bio.sunysb.edu; netfilter@lists.netfilter.org Subject: Re: msn voice chat --- Roy Sigurd Karlsbakk <roy@karlsbakk.net> wrote: > As far as I'm concerned, MSN telephony, and voice > chat, uses SIP, not > h.323, and SIP also needs a helper module the same > way as pptp, ftp, > irc etc I am fairly sure that cronos has written a helper module that can be downloaded and tested if one was curious.
