Hi, I need to get IP port forwarding working ASAP on my 2.2.1-ac5-kernel system. However I'm new to the 2.2.x masq and/or port fw stuff and I can't find a solution to my problem myself.
The installed version of ipportfw is 1.11-7, ipfwadm's version is 2.3.0, and ipchains' version is 1.3.8, 27-Oct-1998. This is the rule I'd like to establish: ipportfw -A -t <external ip>/21 -R 192.168.1.1/21 I compiled support for IP masquerading and port forwarding into modules, and I've loaded them: Server:/usr/doc/ipmasq# lsmod Module Size Used by ipip 4872 0 (unused) ip_masq_user 2608 0 (unused) ip_masq_mfw 2992 0 (unused) ip_masq_ftp 2216 0 (unused) ip_masq_autofw 2196 0 (unused) ip_masq_portfw 2232 0 (unused) [...] However if I execute the above ipportfw line I get ipfwadm: setsockopt failed: Protocol not available Why does it say "ipfwadm"? "string" suggests ipportfw does NOT call "ipfwadm" but that it's a message that ipportfw itself prints to the console. If I execute "ipportfw -L" I get Could not open /proc/net/ip_portfw Indeed, there ain't such a file. Can it be that I have an incorrect version of ipportfw installed that doesn't work with 2.2.x kernels? There's another problem I've just discovered: Altho IP masquerading seems to work fine (I can surf the web and ping other hosts,) I can't seem to be able to send mail (I sent this message by telnetting into a Unix host I have an account on.) Each time I contact our SMTP server it tries to run the AUTH service on my gateway host. Even if I allow the service to be run the message is not accepted. HOWEVER if I manually telnet into the SMTP server and deliver my message this way, it DOES work. What's going on??? Hope someone can help me.... Ralf -- Ralf G. R.
