[ubuntu-in] multiple lan problem

[Ritesh Sinha]

Amit,

I would suggest that you run through this guide once and see if all
steps have been followed:

https://help.ubuntu.com/community/Internet/ConnectionSharing

If it doesn't break your network to start from scratch, consider
following the document and let us know.

Regards,

Ritesh
