ipmasqadm portfw

[Elm Gysel]

(sorry for the wrong subject on previous post!)   Hi,   I'm using kernel 2.2.14 and I have a problem with ipmasqadm portfw. When I try to add a rule for forwarding a port I get the following error : ipmasqadm portfw -a -P tcp -L 212.69.202.112 8002 -R 192.168.1.10 8002 portfw: setsockopt failed: Invalid argument when I try to get get a list I get : [EMAIL PROTECTED] 09:34:06 /server/kernel/linux-2.2$ ipmasqadm portfw -l portfw: setsockopt failed: Invalid argument Could not open "/proc/net/ip_masq/portfw" Could not open "/proc/net/ip_portfw" Check if you have enabled portforwarding From what I understand from searching mailing lists and so on I don't have this aspect commpiled into my kernel. This is the .config file : <cut> # # Networking options # CONFIG_PACKET=y CONFIG_NETLINK=y CONFIG_RTNETLINK=y CONFIG_NETLINK_DEV=y CONFIG_FIREWALL=y CONFIG_FILTER=y CONFIG_UNIX=y CONFIG_INET=y # CONFIG_IP_MULTICAST is not set # CONFIG_IP_ADVANCED_ROUTER is not set # CONFIG_IP_PNP is not set CONFIG_IP_FIREWALL=y CONFIG_IP_FIREWALL_NETLINK=y CONFIG_NETLINK_DEV=y CONFIG_IP_TRANSPARENT_PROXY=y CONFIG_IP_MASQUERADE=y # # Protocol-specific masquerading support will be built as modules. # CONFIG_IP_MASQUERADE_ICMP=y # # Protocol-specific masquerading support will be built as modules. # # CONFIG_IP_ROUTER is not set # CONFIG_NET_IPIP is not set # CONFIG_NET_IPGRE is not set # CONFIG_IP_ALIAS is not set CONFIG_SYN_COOKIES=y <cut> I can't see the option CONFIG_IP_MASQUERADE_MOD so no CONFIG_IP_MASQUERADE_IPPORTFW aswell. So I suppose I need to recompile this kernel? if so... Can I just compile a 2.4 version to upgrade from this 2.2 version? Is there any way not to break things apart if I compile this new kernel? Or is the best way to go just to keep the old .config at hand when configuring the new one? Thx! khb
