 Subject:  Can't ping OPT1 interface from self
 Date:  Thu, 16 Dec 2004 22:53:35 -0800
I have a soekris 4801 with m0n0wall version 1.1.

Using the diag_ping.php I can ping the LAN interface, the WAN 
interface, but not the OPT1 interface (I can't seem to get anything 
through the interface either).

The ping results is

   ping: sendto: Can't assign requested address

The interfaces_opt.php?index=1 page has

  Enable Optional 1 Interface (checked)
  Description: OPT1
  Bridge with: none
  IP address:  xxx.xxx.114.8/29

My intention is to put the DMZ on xxx.xxx.114.8-16

My public addresses are xxx.xxx.114.0/25

LAN is

and I have a static route for

Using exec.php here is the output of netstat -nr

Obviously, I must have done something wrong in configured the OPT1 
interface, but I can't for the life of me figure out what it is.

Again, a summary is that the soekris box can ping its LAN and WAN 
interfaces ( and xxx.xxx.114.2 respectively) but can't 
ping its OPT1 interface, xxx.xxx.114.8

Any help would be, well, helpful.
