H323 with 2.4.x kernel

I think I have seen this subject before but I don't remember any answers. according to a post in http://home.indyramp.com/masq/ The poster said that there are H.323 modules for 2.4.x kernels and provided a link to http://www.netfilter.org/documentation/pomlist/pom-extra.html#h323-conntrack... Has anyone made this work in SuSE? The info provided there is too cryptic for me. how can this be applied in SuSE using SuSE Firewall2? Damon Register
