Working in new IP segment, But Product configured with another IP??

Dear all,

We have installed one of our product in a HP PC server(DL380G5)/SUSE 10 SP1 (2 network cards) with an IP address 10.18.7.25. The Product is working fine.

Now for giving a internet based demo, we have moved to a different network(192.168.50.*)

For the demo, we want to use 192.68.50.* series as We can not change the IP address of Product config as its complex and we are not very sure of the success rate & we do not have time to do reinstallation.

eth0 - 10.18.7.25 & eth1 - 192.168.50.33

Is it possible to use 192.168.50.* address to use the product with out changing the IP address of the product installed??

The web page is working fine, if we use in standalone http://10.18.7.25/main/ssologin, but if i use http://192.168.50.33/main/ssologin, the first page is coming , but logsout automatically & comes back as http://10.18.7.25/main/ssologin.

Is there any solution with respect to Unix environment??

We have tried alaising, IP forwarding techniques to use the current segment, but its not working.

Thanks,
Jagan
