	inet 127.0.0.1 netmask ff000000 
bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
	inet 192.168.0.2 netmask fffffff8 broadcast 192.168.0.7
	ether 0:3:ba:cd:9e:94 
qfe0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
	inet 172.16.72.244 netmask fffffff0 broadcast 172.16.72.255
	ether 8:0:20:cc:eb:b7

and the defaultgateway are as below:-

Code:
#cat /etc/defaultrouter

172.16.72.241

and the problem is, when both network card connected to the LAN the problem as show below:-

Code:
#/usr/sbin/ping 172.16.224.45
no answer from 172.16.224.45

and when traceroute found as below:-

Code:
#/usr/sbin/traceroute 172.16.224.45
traceroute: Warning: Multiple interface found; using 192.168.0.2 @ bge0
traceroute to 172.16.224.45 (172.16.224.45), 30 hops max, 40 byte packets 
 1  192.168.0.1 (192.168.0.1)  0.392 ms !H *  0.259 ms !H

The 172.16.224.45 should go throuh qfe0 but not bge0, but why this happen! Please advise.

NAME

       unbound-streamtcp - unbound DNS lookup utility

SYNOPSIS

       unbound-streamtcp [-unsh] [-f ipaddr[@port]] name type class

DESCRIPTION

       unbound-streamtcp sends a DNS Query of the given type and class for the given name to the DNS server over TCP and displays the response.

       If  the	server to query is not given using the -f option then localhost (127.0.0.1) is used. More queries can be given on one commandline,
       they are resolved in sequence.

       The available options are:

       name   This name is resolved (looked up in the DNS).

       type   Specify the type of data to lookup.

       class  Specify the class to lookup for.

       -u     Use UDP instead of TCP. No retries are attempted.

       -n     Do not wait for the answer.

       -s     Use SSL.

       -h     Print program usage.

       -f ipaddr[@port]
	      Specify the server to send the queries to. If not specified localhost (127.0.0.1) is used.

EXAMPLES

       Some examples of use.

       $ unbound-streamtcp www.example.com A IN

       $ unbound-streamtcp -f 192.168.1.1 www.example.com SOA IN

       $ unbound-streamtcp -f 192.168.1.1@1234 153.1.168.192.in-addr.arpa. PTR IN
