Thx for this Bob,
Before I start, just wanna tell you that I am really gringo, I know
enough about this to get me in trouble...next to nothing. But I want to
do this just to do this. The questions I might ask might seem very
elementary because of my ignorance.
Ok, I do want to make the machines redundant so load sharing is not an
issue here. Sure I would like to learn bout it but whoa...not now.
this zoom router: The Virtual Server Config has in it the following:
ID Public Port Private Port TCP/UDP Private Address
1 53 53 TCP 10.0.0.10
2 80 80 TCP 10.0.0.10
3 25 25 TCP 10.0.0.10
4 21 21 TCP 10.0.0.10
5 20 20 TCP 10.0.0.10
6 53 53 UDP 10.0.0.10
this was what was in it that I had entered a long time ago.
yesterday I just added the following:
1 53 53 TCP 10.0.0.12
2 80 80 TCP 10.0.0.12
3 25 25 TCP 10.0.0.12
4 21 21 TCP 10.0.0.12
5 20 20 TCP 10.0.0.12
6 53 53 UDP 10.0.0.12
sure, I am able to send recieve mail now also in 10.0.0.12 among other
things really but don't you agree that this is wrong?
I really think that when this modem receives a hit for
209.205.179.141:80 let's say, there should only be one private ip w/port
80 listed. Is this correct thinking on handling this considering what I
my simple setup will consist of?
the equipment relevant:
Both boxes have 2 128G Hds... rbmain1 fc2, HDs not raided yet.
rbmain2 fc3, HDs are raided.
I need direction...step by step to accomplish the redundancy etc.
lol first step is to learn all the new terms that bob stated above.
thx
John Rose
