Here is some additional details regarding the problem: https://bugzilla.netfilter.org/bugzilla/show_bug.cgi?id=275 https://bugzilla.netfilter.org/bugzilla/show_bug.cgi?id=302 My problem is though RHEL3 is based on 2.4 its network is based on 2.6 which screws things up. RHEL4 is based on 2.6 but it doesn't work there either. The 2.4.29 works but it kills all of the RHEL3 applications because of an incompatibility with glibc. If you have an older kernel that you can go back to or if you can use the vanilla kernel under 2.4.29 then you can get it to work. Otherwise we will have to await the changes from the Netfilter team. Phil and Harold have been a big help in getting to the cause (and getting me some additional experience in compiling kernels). Gary > -----Original Message----- > From: Gary W.
