The 1st row is for my router and the 2nd row is for my LAN. What's wrong? Is my IP addressing and subnetting wrong? I already checked my configuration.

Your addressing is indeed wrong :-(

First entry is correct, but second is fundamentally wrong. Prefix and mask is ok, but network and range is not. You cannot have a network .4 with a prefix of 27.

27 prefix says - 27 most significant bits of address specifies network. Rest of 32 bits is filled with 0. So last octet must be: xxx00000. When you entered your second ip address, router calculated network address for it (cleared last 5 bits) to be 192.168.1.0, which is the same as your first network, hence 'overlapping' error.

thank you sir for the reply i'm still very new to this topic and for me it is just too hard to understand yet but i'm not giving up ;) so can you suggest me sites/resources that i can review about this topic, or the best practices for ip address of wan and lan! and i only derived that IPs with my own perception since for the 1st row thats for my wan w/ 2 usable ip's is enough and for my lan i got 30 host so i just continue it...because i think will not waste any ip's am i right?

http://en.wikipedia.org/wiki/Subnetwork should get you started. – wmz Aug 10 '12 at 23:33
    

Actually, you could have done it the other way: 192.168.1.0/27 and 192.168.1.32/30.

While this may answer the question, it would be a better answer if you could provide some explanation why it does so. – DavidPostill Feb 5 at 11:53
