Here too. I can compile the thing, but it won't work. I get messages in syslog like : Feb 1 16:21:01 router kernel: ip_conntrack_pptp.c: bad csum Feb 1 16:21:50 router last message repeated 3 times The ip_conntrack|nat_pptp patch downloaded from www.impsec.org for kernel 2.4.17 worked for me, but I need to compile a newer kernel and I can't get it done anymore. Is there someone who has got this working ?? Besides, isn't there anyone that hasn't got problems when compiling iptables-1.2.7a ? It complains about not having if_name and if_index defined in ipt_ROUTE.h. (plain kernel-2.4.20, patched with pom-20030107). In ipt_ROUTE.h I don't see an if_index nor if_name, however there is an ifname. So I created the ifindex myself (unsigned int ifindex, it was somewhere in the past pom's). And in the libipt_ROUTE.c file (iptables package) I changed all instances if_name and if_index to ifname and ifindex. I don't know if that was the right thing to do, but now iptables compiles and so far I don't have any problems with it. Gr, Rob
