Hi, I have a small LAN at my home! and also a cisco router (soho 91). i have a nat and a dhcp running on the router! but when i connect the router directly to my modem - all the pc's cant reach the internet! when i connect only 1 pc to the modem it reaches the internet. this is my main configuration:
ip address 10.10.10.254 255.255.255.0
ip nat inside
no cdp enable
hold-queue 100 in
hold-queue 100 out
description ***link to cables via CM***
ip dhcp client class-id eth1
ip address dhcp
ip nat outside
no cdp enable
ip dhcp pool CLIENT
network 10.10.10.0 255.255.255.0
dns-server 18.104.22.168 22.214.171.124
lease 0 2
ip route 0.0.0.0 0.0.0.0 ethernet 1
i have not configured dialer here,beacause it is automatic! when i connect 1 pc to the modem i have internet (without create dialer).
i will be very glad if someone can help me by solving this problem! if someone can redirect me to a web site which explains it i will be also glad thanks!!!

it doesn't appear that your natting is fully configured. you'll need to create an ACL for the hosts that you want to nat (your 10.10.10.0/24 network) and add the nat overload statement to the config.
something like this:
access-list 10 permit 10.10.10.0 0.0.0.255
ip nat inside source list 10 interface Ethernet1 overload
EDIT: Also, you'll want to eventually modify your DHCP scope to exclude the address that you've used for the router's own interface E0, otherwise you'll get a conflict (if you end up with more than 253 hosts on your network, which probably won't happen, but still). It's always a good idea to exclude something like the beginning and ending 10 addresses or so for static purposes like routers, printers, servers, etc.
