IP Networking

After i connect to my openbsd router, i cannot ping the gateway neither nor wired or wireless.
I don't know what happen. My /etc/ppp/ppp.conf consists of add! default HISADDR.
Shoudl i change my rl1 to another subnet ? Thanks

Certainly no two interface adapters address ranges/subnets should overlap.

Reconfigure rl1 way out of the way so we can solve rl0 first.

I have change that but i don't know whether my configuration is correct.
/etc/hostname.rl1 :
inet 192.168.1.5 255.255.0.0 NONE
/etc/dhcpd.conf :
subnet 192.168.0.0 netmask 255.255.0.0
option routers 192.168.1.1;
range 192.168.1.3 192.168.1.5;
By the way, i have to say a billion times of thanks to you. YOu are the only person who willing to help me.
How can i return help to you ?

post complete results of "ifconfig -a", it's difficult to see complete picture with fragmented postings.

I don't know much about subnet. Thanks.
