 | Finally, I have done some debugging.
 | 
 | - In sifproxyarp(), arpmsg.hwa contains the correct MAC address.
 | - Socket write() succeeds with 112 bytes written, that looks good.
 | - If I comment out the socket write(), and manually enter the
 | arp entry (arp -s 10.0.0.192 <mac> pub proxy) then the kernel still
 | does not respond to arp who-has requests.
 | 
 | Now, some questions:
 | 
 | - The proxy arp entries are not visible in `arp -a'. Should not they
 | be visible? For example, on Linux they are visible.
 
 should be visible I think. do you have a configuration for me to test?
 
 | - Once I add an arp entry with `arp -s 10.0.0.192 <mac> pub proxy'
 | I cannot remove it later. (arp: delete: can't locate 10.0.0.192)
 | Is this normal?
 
 Works for me:
 
 [DING!] 2502#arp -s 192.168.2.200 00:01:02:03:04:05 pub proxy
 [5:00pm] 2503#arp -a

 | test it?
 
 Yes, just send me an example setup and I will test.
