FTP and Masquerading

[Muaddib]

Any kernel gurus out there experienced a problem compiling IP_CONNTRACK_FTP into the kernel and getting the module to load properly??

I am currently using a 2.4.16 kernel and I have compiled in all modules relating to ftp masquerading. The problem is this server is our firewall and our ftp connections to the outside world work but we can't do ls, mget, etc. It gives an illegal port command error. When I try to insmod the module I get the following unresolved symbol errors:

ip_conntrack_helper_register_R1844eee6
ip_conntrack_helper_unregister_R40d1f34f
ip_conntrack_expect_related_Raed0cb12

With older kernels (prior to 2.4.x) a different module was used on our server and allowed the ftp masquerading to work just fine. Any ideas????

Hi,

I've compiled and used that module and almost all the other netfilter ones for every kernel from 2.4.0 up to 2.4.17 and never had any problems.

Does it make any difference if you modprobe it rather than use insmod ?
