SPAMD & MultiWAN

[sergu61]

I have two WAN interfaces: WAN and OPT1.
Below I have described the movements with which I made ​​spamd run on two WAN interfaces.

1. I created in a folder /usr/local/pkg file spamd.inc.patch:

*** spamd.inc Tue May 10 16:05:26 2011
–- spamd.inc_multiwan Tue May 10 16:10:45 2011

  case 'nat':
  $natrules .= "\n# spam table \n";
                  $wanif = get_real_interface("wan");
+                $optif = get_real_interface("opt1");
                  $natrules .= "table <whitelist>persist\n";
                  $natrules .= "table <blacklist>persist\n";
                  $natrules .= "table <spamd>persist\n";
                  if(file_exists("/var/db/whitelist.txt"))
                          $natrules .= "table <spamd-white>persist file "/var/db/whitelist.txt"\n";
                  $natrules .= "rdr pass on {$wanif} proto tcp from <blacklist>to port smtp -> 127.0.0.1 port spamd\n";
+                $natrules .= "rdr pass on {$optif} proto tcp from <blacklist>to port smtp -> 127.0.0.1 port spamd\n";
                  $natrules .= "rdr pass on {$wanif} proto tcp from <spamd>to port smtp -> 127.0.0.1 port spamd\n";
+                $natrules .= "rdr pass on {$optif} proto tcp from <spamd>to port smtp -> 127.0.0.1 port spamd\n";
                  $natrules .= "rdr pass on {$wanif} proto tcp from ! <spamd-white>to port smtp -> 127.0.0.1 port spamd\n";
+                $natrules .= "rdr pass on {$optif} proto tcp from ! <spamd-white>to port smtp -> 127.0.0.1 port spamd\n";
                  if($config['installedpackages']['spamdsettings']['config'])
                          foreach($config['installedpackages']['spamdsettings']['config'] as $ss)
                                  $nextmta = $ss['nextmta'];
                  if($nextmta <> "") {
                          $natrules .= "rdr pass on {$wanif} proto tcp from <spamd-white>to port smtp -> {$nextmta} port smtp\n";
+                        $natrules .= "rdr pass on {$optif} proto tcp from <spamd-white>to port smtp -> {$nextmta} port smtp\n";
                  }

break;

2. I created in a folder /usr/local/sbin file spamd_patch.sh:

#!/bin/sh
SUCCESS=0
word=opt1
filename="/usr/local/pkg/spamd.inc"
cd /usr/local/pkg
grep -q "$word" "$filename"
if [ $? -eq $SUCCESS ]
then
  /etc/rc.filter_configure_sync && pfctl -f /tmp/rules.debug
else
  patch -i /usr/local/pkg/spamd.inc.patch && /etc/rc.filter_configure_sync && pfctl -f /tmp/rules.debug
fi
exit
