  > Show log entries in reverse order (newest entries on top)
  Number of log entries to show:
  > Log packets blocked by the default rule
Hint: packets that are blocked by the implicit default block rule will not be logged anymore if you uncheck this option. Per-rule logging options are not affected.
  > Show raw filter logs
Hint: If this is checked, filter logs are shown as generated by the packet filter, without any formatting. This will reveal more detailed information.
  > Resolve IP addresses to hostnames
Hint: If this is checked, IP addresses in firewall logs are resolved to real hostnames where possible.
Warning: This can cause a huge delay in loading the firewall log page!
  onClick="enable_change(false)"> Enable syslog'ing to remote syslog server
Remote syslog server
IP address:  
Port:   (optional; default = 514)
> system events
> firewall events
> DHCP service events
> Captive portal
> PPTP/L2TP VPN events
> Bind to LAN interface only
This option can be useful when trying to send syslog data through a VPN tunnel terminated on the WAN interface.
 
  Note:
syslog sends UDP datagrams to port 514 on the specified remote syslog server. Be sure to set syslogd on the remote server to accept syslog messages from m0n0wall.
