LinkSys Forwarding?

[mikeshn]

Hi

I run Red Hat 7.3 box. I use LinkSys DSL router MODEL: BEFSR41.
So I want to enable the ssh connection to the box using port 22.

In order to do that, I need to make changes to the FORWARDING option in LinkSYS

So I did:

#1 htp://192.168.1.1 // login
#2 click Advance
#3 click Forwarding
#4 Enter Port 22 on Service Port Range, looks Like
Service Port Rande 0 ~ 22 IP Address 192.168.1.1
#5 Click APPLY

However, when I try connect remotely to the box it can't connect..
I typed the command to connect: ssh -l my_Ip_address

It doesn't work ..

Can someone give me a hint on that?

Thanks

M.S.

The port should be forwarded to the IP address of the Linux box.

When I forward with the same router I have to forward to the IP address of the box, which is 192.168.1.100 for me.

make sure you have SPI disabled. if it's enabled, it disables all port forwarding.

Um, never heard of that before!

ditto, WTH is SPI?

if you havent upgraded the firmware, older firmware models had problems forwarding to static IP's if DHCP was enabled.

also you have it set to forward to your linksys router, and the linksys router doesn't except connections on port 22 , you need to forward to your linux boxes IP address.

SPI = Stateful Packet Inspection

Linksys has a piss poor implementation of it too. It's virtually worthless.

I know what it is, but I never heard of it disbaling port forwarding.
The linksys may not do SPI very well, but disabling port forwardiong. I dont thinks o.

I know that it gave me some problems once but I can't remember what it did exactly. I do know that it supposedly makes the router less stable.

from here

The SPI (Stateful Packet Inspection) option is currently an experimental feature. If you enable this feature, it will DISABLE THE FORWARDING FEATURES. The reason forwarding is disabled is to test the SPI and make sure forwarding is not a factor. In the released version, forwarding will not be disabled when SPI is enabled.

The SPI feature can be tested by using applications like Netmeeting and other applications that use many ports dynamically. SPI will open the ports as needed as long as the data transfer session originates from a LAN side computer. When the initial data transfer comes from the WAN side of the router, the normal port Forwarding feature must be used (however, remember that Forwarding is disabled in the BETA).

well, just looking at the version list, SPI was removed in firmware v1.43. so nevermind if your firmware is updated to the latest. i dont know about anyone else, but when i had SPI enabled, i was unable to forward ports.

What is SPI ? and WHere I can enable it?
