Bug 18895

Summary: 'fe80::<ether>' cannot be used in "via"
Product: Base System Reporter: trost <trost>
Component: binAssignee: freebsd-bugs (Nobody) <bugs>
Status: Closed FIXED    
Severity: Affects Only Me

Description trost 2000-05-30 00:00:00 UTC 
	If an address starting "fe80::..." is used as the interface in
	an ip6fw "via" clause, the address is not recognized but is
	(apparently) interpreted as the hostname "fe80".

Fix: 

Prepending a zero to the front of the address causes the desired
	interpretation.  However, the firewall rule still doesn't work
	when that is done, so I switched to the interface name instead.
How-To-Repeat: 
	ip6fw add 55555 deny all from any to any via `ifconfig -au |
				fmt 1 | grep fe80 | head -1`
