Good evening everyone, whereever you may be. I have a little scenario I
would like you to consider. It's two networks linked together through a
server that is not directly connected to the net. Here is the topology:
Internet -> Server 1: 203.29.98.1 -> Server 2 (NIC 1): 203.29.98.2 -> Server
2 (NIC 2): 203.29.98.254 -> Client 1: 203.29.98.253
Server 1 can see Server 2 (NIC1) OK but can't see Server 2 (NIC 2). As a
result, Client 1 will not be able to see the Internet (I assume). Another
Client (Client 2) - (203.29.98.6) which is part of the network that Server 1
and Server 2 (NIC 1) can still see the net OK but can't see Server 2 (NIC
2).
I assume this is a routing thing. What do I have to do, and on which
machine, to get the network running correctly?
Any assistance appreciated.
Regards
Dan

What are the netmasks for each network?
Which machine is connected to the Internet and how?
Are you running RRAS on these servers?

They are all netmask 255.255.255.0 (203.29.98 is a class C), Server 1
(203.29.98.1) is connected to the net via an ISDN TA. Aside from the net
connection, on the internal network 203.29.98.6 can't ping 203.29.98.254,
(NIC 2 on Server 2) but CAN ping 203.29.98.2 (NIC 1 on Server 2) RRAS is
not installed on any of the PCs.

If you use 255.255.255.0 then 203.29.98.1 expects that 203.29.98.254 is
within its network, but this is not the case. You must use two subnets with
netmask 255.255.255.127, assign Server 1 (203.29.98.1) as default gateway on
each client and also aktivate IP-forwarding between the two NICs.
If you want to open both subnets, I do not understand why you don't just use
one NIC in server 1. Am I missing something?

In order to route properly, the router must be between two DIFFERENT
subnets. In your case, you are using server2 to route between NIC1 and NIC2,
but they are on the same subnet, so it will not route. You need to either
put them all into the same network, with just one NIC in server2 and all
clients on the same net with current netmask of 255.255.255.0, or split them
into smaller subnets. If you split it in half, assign the first net IP's
203.29.98.0-127 with netmask of 255.255.255.128, and the second net IP's
203.29.98.128-255 netmask 255.255.255.128 as well. Keep in mind on each
subnet the first and last IP's are not usable, in example above the second
net cannot use IP's 203.29.98.128 or .255

Subject: is this feasible ?
From: Mark DeWar <inetmail@fiber-net.com>
Date: Sat, 25 Jul 1998 10:46:58 -0400
We took a direct lighting strike (florida is so wonderful at times) and some
equipment will have to be replaced.
Since I have to replace equipment was thinking of doing the following.
Would it be worth it or not ?
Moving all my computones and cisco2511 to rj45 with transceivers. and
putting them into a 10hub.
moving my computers that we use for mail,web,dns&radius to 10/100 cards and
plug them into a 100hub and put the hub into a 10/100 switch.
and putting the 10hub into the 10/100 switch.
it looks like the strike traveled thru the bnc as two hubs were blown. and
this way one bad nic or cable section won't bring down the whole thing.
TIA

Several months ago there was a discussion about access control list, one of
which showed how to block everything incoming to the router from the net
except the desired ports.
I want to use such an ACL and the one I've created works for all the ports I
want except FTP - people can reach our servers but cannot view the files in
the directories, and similarly I can reach and outside FTP server but cannot
view the files etc.
I've permitted tcp any any on ports 20 and 21 but i am clearly missing a
port.
All help gratefully received.

Thanks for that, I'll try that later today. The reason for wanting to dothis is to join a 10Mb coax network to a 100Mb UTP network, otherwise, yesthere would be no point in the whole exercise!

We have a situation where we have 3 9GB drives in aTangent Enterpise Server w/hot swap drives. System isfully redundant.
Drive Configuration:
Partitions:
DISK 0 C:\ FAT 1028 D:\NTFS3342 FREE SPACE=4346DISK 1 E:\ NTFS 4738 FREE SPACE=3977DISK 2 F:\ FAT 4001 FREE SPACE=4714
Tangent says their hardware raid system will cause the C:\NT 4.0partition to be supported and bootable with RAID 5.
QUESTIONS:
1. DO YOU NEED TO PARTITION THE RAID 5 STRIPE SET AS NTFS OR AS FAT?
2. WILL FAT OR NTFS PARTITIONED DRIVES WRITE TO A RAID 5 STRIPE SETWHICH IS EITHER FORMATED AS FAT OR NTFS [EXCHANGABLE]? AND DOESTHAT EFFECT RECOVERY SHOULD A DRIVE GO DOWN?
3. ARE RAID 5 PARITY STRIPE SETS ASSIGNED A DRIVE LETTER OR DO YOULEAVE THEM WITHOUT ANY?
4. DOES IT MAKE MORE SENSE TO CREATE A RAID 1 MIRROR SET FOR THE C:\ DRIVE. THE SAME FOR THE F:\FAT DRIVE PARTITION & WHAT'S LEFT OVER ASRAID 5 PARTITIONS.
Thanks in advance for your imput on this matter. All constructive comments would be most appreciated.
