My Cisco Router 837 have two virtual ethernet interfaces, ethernet 0 and ethernet 2, and more four physical fastethernets. When I configure the two interfaces, one as 192.168.2.1 and other as 192.168.4.2, my server ERP loses connectivity with IP 192.168.2.1 (ERP application have 192.168.1.120 IP address). Could you tell me what is happening? I think that Cisco 837 segments two ports at each network ( 192.168.2.1 and 192.168.4.2). What am I supposed to do to have the communication between the two networks and my erp doesn't lose the communication as well?
Thanks.
Best Regards.

Hi, the 837 should not have two virtual ethernet interfaces. Please send "show diag" and "show run" to identify what you have.

Hi,
That would be use of the "DMZ" features, see:
http://www.cisco.com/en/US/docs/ios/12_3/12_3x/12_3xr/dmz_port.html
When used, ethernet2 is physically connected to fasternet4.
Just make sure that router and servers connected have consistent network/mask, and you should be fine.
Please rate post if it helps!

Just assign IP address, nothing else is required.
