Interesting issue - OS related?

[SmoothJ]

Well, here is my situation…

I have the following setup at home:

Cisco Modem -> Cisco SA520 -> Dell 2816 -> MBP
(SA520 DMZ)-> Linux web server

I can ping the web server without any issues, however when trying to do a SCP or SSH, the ethernet on the MBP drops and even though I still have a IP, I can't go out or ping. I would have to do a down and up for me to get ethernet connectivity back.

MBP's IP is 192.168.1.0/24
Server's IP is 10.1.1.0/8

Anyone have an idea?

one thing i do know is that the ip's are in 2 seperate class's

192.168 is one bracket and the servers is a different...

basically like saying 192.168. is class 1 (FOR EXAMPLE)
and 10.0 is class 2 - if i remember rightly then dont play well together!!!

does your router not auto assign ip's...from DCHP???

That indeed sounds like it would be a problem on your end, specifically on your MacBook. Sorry, I can't say how to fix it aside from trying another computer to make sure.

It is auto assign, however I have routing turned on between the two networks. So thats why I am able to ping and etc.

I have another MBP from work that I can try. If it works its one of several things; the drivers for the chipset are messed up, my NIC is having issues, or I need to do a fresh install (even though the system is a couple of days old).

However if it was the NIC then how come I can ssh and scp to external areas out in the internet, like my webserver.
