Modem in bridge mode should not be doing anything but
giving you a live IP
(internet rout able, not 192.168.x.x) on the WAN port
of your router.
Also, if you were running a 192.168.x.x/24 net from
the modem to router's WAN
and then a 192.168.x.x/16 on the router's LAN side no
wonder you had troubles. 2
interfaces, same subnet, router in the middle- where
would the router send the
packet? Since "default gateway" (LAN to WAN, WAN to
LAN) means "if this packet
is destined for a subnet outside of the current
subnet, so send it to gateway to
be forwarded to outside subnets". Using the same
subnet on both LAN & WAN (in
gateway mode) would mean nothing routes across the
router because from the
router's & client systems' logic "Is this destined for
my subnet? Yes." there is
no reason to.
1. Modem - Bridge mode
2. Router WAN - PPoE, give it your DSL user & pw
3. Router LAN - 10.0.0.1/8
4. DHCP pool, start: 10.0.0.2, # of clients: whatever
you need.
If you had followed this method you would not have had
an issue with your
192.168.x.x setup assuredly with a CIDER /16 but for
sure no problems with a
standard /24 class C subnet since the is nothing magic
about class A subnet that
fixed your original issues. Not too mention all this
hassle is why DHCP is
preferred over static to begin with since setting up
the router &/or DHCP server
sets up every one else.
