I used CVS/POM and patched my vanilla 2.4.20 kernel to include support for ip_conntrack_pptp and ip_nat_pptp, but after I do this, the MASQUERADE target no longer works. lsmod shows both modules load successfully as well as the ipt_MASQUERADE, but when I run my nat rule: iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o eth0 -j MASQUERADE it just says Invalid Argument. I have two identical kernels, one with the pptp patch applied, one without, and the one without allows the MASQUERADE target just fine. Is there a known bug with the latest CVS pptp-conntrack-nat patch interfearing with masquerading? Thanks. -- Mike Machado mike@xxxxxxxxxxxxx InnerCite Inc. Engineering Director / CTO
