Hi have a solaris server with the following IP

192.168.0.85

, but anybody can login in using

172.19.0.85

, and the

ifconfig

command does not show the

172.19.05

.

# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 192.168.0.85 netmask fffffe00 broadcast 192.168.1.255
        ether 0:21:28:7e:3a:54
sppp0: flags=10010008d1<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST,IPv4,FIXEDMTU> mtu 1500 index 3
        inet 192.168.224.2 --> 192.168.224.1 netmask ffffff00
        ether 0:0:0:0:0:0

How come this is possible?

Network address translation on the router?

Hi

Please explain, I dont know if there are any, these are solaris hosts

172.19.0.85 , although a class B private address, is not on the same subnet as 192.168.., so it needs a router to connect. That router could apply NAT.

is there anyway to remove this feature in the router?

Yes, if you know how to configure the router.
