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 126.96.36.199
secondary DNS address 188.8.131.52
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.
