Hello Koti,
I'll try to answer some of your questions:
1)As the reginfo,secinfo files maintained can I remove gw/acl_mode=1 parameter ? YES, but there is no need for doing this!
...will that means 8+2+1 means satisfying the above 3 lines except condition 4 ? YES
For all other questions I'm also interested in!
Regards,
Karlheinz
