im not very familiar with routers/switch .. so need basic help.
i have a cisco 1800 router that i need to connect to calbe modem that is running in bridge mode.
all i was given by isp is ip address. gateway / mask
can i connect the 1800 directly to the cable modem or do i need a home router that would give ip address to the router interface?
Solved! Go to Solution.
You can connect it directly.
If you do not have experience with cisco routers, get someone that has it, that will save you much time loss and frustration.
Otherwise for home use get a linksys router that is easy to to setup with GUI.
thanks but ,,from what i gather its a simple config.. anybody else. .can help..
dsl modem > (netgear modem doing natting/dhcp) > 1841 > WLC 2504
im just looking help configuring 1841.. thanks
this is a new setup along with wlc,
not for home. i can get wlc support from cisco ,but they wont support router as its not under contract
so at the moment only modem and netgear router is working.
i was told wlc needs a layer 3 device to connect to modem. (so i found a old 1841 sitting around )
thus need to configure it.
Make it simple
just give ips to router interfaces
enabling ip routing
give default router to netgear modem
ip route 0.0.0.0 0.0.0.0 (netgear Modem IP)
, thanks for the help
i got the following config. am i correct in assuming, if i connect a laptop to f0/1 port with crossover, it should get an ip and show be able to get on the net without issue? (cause i am not).. what do you think. he problem is i have the wlc 2504 connected to f0/1, however when i connect ap to wlc poe port they dont get ip.. (wlc is configured with routers f0/1 address as dhcp server address.

sorry i didnot get your point
u mean it not working if u are connecting your pc to fa 0/1
if that the case
mentioned above u were telling u have isp modem that responsible for natting dhcp (am i rite or wrong)
hav u connected that to your router.
if you have connected to that to your router what that modem lan ip and wan ip.
r u able to ping that......
leave wlc rite now start for scratch.
i am getting 1841 to do natting (isp modem is working in bridged mode (dpc3825)
this is working fine, as i can ping 18.104.22.168 from both 1841 and wlc, however problem im having is dhcp side of the config...
none of the device are getting dhcp ip address. if i connect a laptop to f0/1 (crossover) shouldn't it get a ip from router and be able to get on the net ? as per statement below?
the issue here is the ap connected to wlc aren't getting ip from 1841, ... i dont see anything wrong with my config (pasted above)...
Also your configuration seems ok
run this command
show ip interface bried
if u see both interface are administrative down then
go under each interface
interface fa 0/1
intface fa 0/0

think maybe i was missing below, i didnt exclude 1.1 add. could that be..
ip dhcp exclude address 192.168.1.1 192;168.1.10
i have it connected to wlc and ap via a switch. everything is working now. thanks Jawad.
