Above, address 207.155.75.161 has a gateway of 127.0.0.1. Is this right/wrong?
How did it happen? Here is my statement:
ifconfig eth0 207.155.75.161 207.155.75.162 netmask 255.255.255.224
route add -net 207.155.75.128 -netmask 255.255.255.224 207.155.75.162
A little more info.: eth0 is used to sub-divide 207.155.75.128/26 into 2 /27's.
One of the /27's (207.155.75.160/27) is used to pivot the other (207.155.75.128/27). There is a remote router (207.155.75.162) which has an ethernet port
(207.155.75.129) which feeds the rest of the LAN (207.155.75.130-158).
Please let me know if you think this is right/wrong and in what ways.
Thanx,
Randy Katz
PS - The reason I'm asking is there was some sort of glitch and when I reset
eth0 (ifconfig eth0 delete) and reissued the command (ifconfig
eth0 207.155.75.161 207.155.75.162 netmask 255.255.255.224) it came
back up...
