I'm not certain I understand the need for WINS Server.
I have freeswan and I can broadcast ping one subnet 192.168.1.255
PING 192.168.1.255 (192.168.1.255) from 64.105.122.138 : 56(84) bytes of data.
64 bytes from 66.114.66.239: icmp_seq=1 ttl=255 time=30.4 ms
64 bytes from 66.114.66.239: icmp_seq=2 ttl=255 time=28.5 ms
64 bytes from 66.114.66.239: icmp_seq=3 ttl=255 time=30.6 ms
But not another
www2:~ # ping -b 192.168.0.255
PING 192.168.0.255 (192.168.0.255) from 64.105.122.138 : 56(84) bytes of data.
--- 192.168.0.255 ping statistics ---
4 packets transmitted, 0 received, 100% loss, time 3015ms
And yet both are only attached by VPN.
www2:~ # route -n |grep ipsec
64.0.231.99 64.105.122.137 255.255.255.255 UGH 0 0 0 ipsec0
66.114.66.239 64.105.122.137 255.255.255.255 UGH 0 0 0 ipsec0
64.105.122.136 0.0.0.0 255.255.255.248 U 0 0 0 ipsec0
192.168.1.0 64.105.122.137 255.255.255.0 UG 0 0 0 ipsec0
192.168.0.0 64.105.122.137 255.255.255.0 UG 0 0 0 ipsec0
What can cause this? The 192.168.0 is behind a FreSwan System with a gateway looking like this
216.254.100.195 64.0.231.97 255.255.255.255 UGH 0 0 0 ipsec0
64.105.122.138 64.0.231.97 255.255.255.255 UGH 0 0 0 ipsec0
66.114.66.239 64.0.231.97 255.255.255.255 UGH 0 0 0 ipsec0
64.0.231.96 0.0.0.0 255.255.255.248 U 0 0 0 eth1
64.0.231.96 0.0.0.0 255.255.255.248 U 0 0 0 ipsec0
10.0.0.0 64.0.231.97 255.255.255.0 UG 0 0 0 ipsec0
192.168.1.0 64.0.231.97 255.255.255.0 UG 0 0 0 ipsec0
192.168.0.0 192.168.0.100 255.255.255.0 UG 0 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 64.0.231.97 0.0.0.0 UG 0 0 0 eth1
This VPN Server is not the default route for the 192.168.0.0 subnet machines. The hosts behind it
look like this in their routing:
192.168.0.110 0.0.0.0 255.255.255.255 UH 0 0 0 eth0
192.168.0.130 0.0.0.0 255.255.255.255 UH 0 0 0 eth0
192.168.1.0 192.168.0.130 255.255.255.0 UG 0 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.0.100 0.0.0.0 UG 0 0 0 eth0
It can't broadcast to the 192.168.1 network
[root at superman /root]# ping -b 192.168.1.255
PING 192.168.1.255 (192.168.1.255) from 192.168.0.110 : 56(84) bytes of data.
--- 192.168.1.255 ping statistics ---
3 packets transmitted, 0 packets received, 100% packet loss
But it can ping an individual host in the 192.168.1 network
PING 192.168.1.100 (192.168.1.100) from 192.168.0.110 : 56(84) bytes of data.
64 bytes from 192.168.1.100: icmp_seq=0 ttl=125 time=27.1 ms
64 bytes from 192.168.1.100: icmp_seq=1 ttl=125 time=25.9 ms
64 bytes from 192.168.1.100: icmp_seq=2 ttl=125 time=27.3 ms
--- 192.168.1.100 ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 25.9/26.7/27.3 ms
