DSL-N :: Please Help Wireless.
A landlord wants me to setup wireless in a large building, I will be employing bigger antennae, and Repeaters.
I want to setup building before buying landline connection, method:
I bring internet to box_1 by GPRS cellphone,
/usr/sbin/pppd connect '/usr/sbin/chat -v "" "AT&F" OK "AT+CGDCONT=1,\"IP\",\"LEMONINTERNET\"" OK "ATDT*99#"' noauth /dev/ttyACM0 921600 defaultroute noipdefault user ppp usepeerdns
Box_1, I want to "pipe" ppp0 to wlan0. wlan0 to Box_2, Ad-Hoc?. Box_2, notebook/laptop has wireless card, I will roam building.
I need to NAT, is this correct?
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -A FORWARD -i ppp0 -o wlan0 -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
tail -f /var/log/messages
local IP address 10.32.204.221
remote IP address 192.168.100.101
primary DNS address 22.214.171.124
secondary DNS address 126.96.36.199
ppp0 Link encap:Point-to-Point Protocol
inet addr:10.32.204.221 P-t-P:192.168.100.101 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1
pppd is always Mask:255.255.255.255
I am reading wireless HOWTO etc., I WANT TO DO MANUALLY.
Can I do this?
route add default gw 192.168.0.1
route add 192.168.0.1 dev ppp0
route add 192.168.0.1 dev wlan0
Any input many thanks, Andrew.
I'm afraid I'm not enjoying networking at the minute.
Because unfortunately I don't quite understand exactly what I am doing, perhaps the best I can do is systematically try options.
I hope somebody could offer some input and perhaps I will learn and understand.
Cellphone won't function as a modem without pppd options defaultroute noipdefault usepeerdns.
Usepeerdns creates an /etc/ppp/resolv.conf file containing two nameserver lines with the addresses supplied by the peer.
Do I need to add a line to /etc/ppp/resolv.conf ?
Perhaps I should be using dhcpd & dnsmasq or something ?
I am trying to gain some understanding.
Any input appreciated.
