configure hp9000 box as a router

[tom quach_1]

Hello,
i have 3 servers (SV1,SV2,SV3)locate out side the firewall,ipaddresses start with 192.168.20.0
inside my LAN there are 8 more hpuxboxes. One box( HP1)this HP1 box has 2 network cards
1 goes to LAN 10.10.2.0 and 1 goes to outside the firewall:
ip 192.168.20.0 ....
subnet 255.255.255.0
gateway 192.168.20.254

iam using this box (HP1) to connect to SV1,SV2,SV3.
LAN:
ip 10.10.2.0...
subnet: 255.255.255.0
gateway:10.10.2.254

is there a way to configure HP1 as a router
so all my HP Boxes can see SV1,SV2,SV3 and vise vesa thru this box HP1.

Thanks for your help,

Tom

If you have two network cards, you are in good shape.

You may find these docs helpful:

Important note: You can't have two NIC cards on the same network. That will stop allnetwork traffic. Though both your addreses are class C, you need to take that into account.

Thanks Steven for the info.
I will try to read this but if you have any shortcut instruction, I would really appreciated.

Hello!

Not clearly undestand what addresses interfaces have in HP1 box. Let it be 192.168.0.1 and 10.10.2.1 (zero host address like 192.168.20.0 is invalid with such subnet mask, because it's the address of entire subnet)

1. Check if ip_forwarding is enabled on HP1.
#ndd -get /dev/ip ip_forwarding
(should return 2)

2. On every client machine in 192.168.20.0 subnet add route to subnet 10.10.2.0 through 192.168.0.1 interface in HP1 box (man route(1M)).
#route add 10.10.20.0 MASK 255.255.255.0 192.168.20.1

3. Similary on all clients in subnet 10.10.20.0
#route add 192.168.20.0 MASK 255.255.255.0 10.10.20.1

4. Try to ping addresses from one subnet to another.

Ops. 10.10.20.* should be read as 10.10.2.* of course.

HiArtyom,

Thanks for your help,
this command route add, i use in windows ENV
but somehow could not think of it in UNIX.
it works well, I could ping from another server in my LAN (HP2) to SV1 and SV2 but not SV3
SV1 ip:192.168.20.1
SV2 ip:192.168.20.2
SV3 ip:192.168.20.4

sub:255.255.255.0
gateway:192.168.20.254

double checked ip, submask,gateway in SV3
and they are correct.

--another small problem:
when telnet 192.168.20.1

#telnet 192.168.20.1
Trying...
Connected to 192.168.20.1.
Escape character is '^]'.

Please type [Return] two times, to initialize telnet configuration
For HELP type "?"

type /
===JetDirect Telnet Configuration===
how can i make the telnet works.

Thanks a lot,

Tom

Tom, please post routing table for SV3. "netstat -rn" command for HP-UX or "route print" for Windows.
What about telnet, everything seems alright. 192.168.20.1 is a JetDirect network printer, and when you try to connect this address, you get into its configuration menu.

Hi Artyom,

here're the result of 2 boxes
the 1st one is ok the 2nd is not.
#netstat -rn

regarding telnet.
192.168.20.1 is not a jetdirect, it is a unix box. I cannot get in
the previous screen was the one i've received when telnet to the unix box.

Tom
