Hi Smiling Dragon,

Thanks.. I'm getting an idea from your reply.

Actually, the aim should be to be able to switch between the devices ( from external to internal network and vice versa) without requiring a maintenance window or risking other network connections. This is a requirement if server in prod will be tested via internal network.

Its quite weird but if we have a setup such this would be very helpful.

IPX_CMD(8)						      System Manager's Manual							IPX_CMD(8)

NAME
ipx_cmd - bridge between Novell's SCMD driver and local IPX network SYNOPSIS
ipx_cmd -A server name [ -l local interface name ] DESCRIPTION
ipx_cmd moves packets from tapN to server and vice versa. It is something like IPX Tunnel, but it uses Novell Netware 5 server Compatibil- ity Mode Driver (AKA Migration Agent) on the other end of wire. You must first configure your kernel tapN device with IPX EthernetII frame and with network number set up on server (you can use kernel autodetection). OPTIONS
-A server name This is IP name of compatibility mode server. You can use DNS name or dotted quad to specify server address. -l local interface name This allows you to specify, which of your IP addresses should be used as IP address of client side of CMD driver. You must configure your tapN device with hardware address 7E:01:AA:BB:CC:DD, where AA:BB:CC:DD is your IP address in hexa. EXAMPLE
If you are on server platan.vc.cvut.cz (147.32.240.81) and your migration agent runs on server boris.vc.cvut.cz, you can configure your system with: insmod ethertap ifconfig tap0 hw ether 7E:01:93:20:F0:51 up ipx_interface add -p tap0 EtherII ipx_cmd -A boris.vc.cvut.cz -l 147.32.240.81 & BUGS
This program was written to satisfy my own needs and should be really improved. At least it should configure tap interface itself. AUTHOR
