What is the overall network configuration? e.g.:
do you have a router?
IP settings---static vs DHCP?
Where is the external internet connection?
what is connected to each card?

I am still having a hard time understanding---please keep short sentences.

Please answer all questions:

what is connected to eth0?

what is connected to eth1?

what is the external internet connection? For example, it might just be an ethernet connection to your company network.

Is the external internet connection set to static IP or dhcp.

there is no internet connection it is standolne server on which i configured 2 lan interface with static ip
eth0 is connected to switch
eth1 is connected to switch

OK---what is the switch connected to? We need a complete desscription of your setup.

I am not familiar with switches---do they require any setup in terms of static vs dynamic IPs?

A switch is kind of just a "smart" repeater for a network... it allows something else to be connected... A typical (home) router supplies a DHCP server, a firewall, 4 hardwired Ethernet ports, and a wireless access point, security setup and QOS services. If you turn off the DHCP server, a router would essentially function like a switch... one that has a wireless access point.

A switch like he's describing would typically be used to extend a router's available hard wired Ethernet ports...
