Hello, I'm a real newbie with arm-linux so I'm sorry if I bother for nothing I'm running a 2.4.0-test6 kernel with patch (kernel linux-2.4.0-test6-rmk6-bluemug3) on a board a with clep7211 and two serial ports I think I compiled the kernel with all the necessary options to do ipforwarding, NAT and so on I set up a network as follows: on ARM server side : ifconfig lo 127.0.0.1 ifconfig eth0 hw ether 11:22:33:44:55:66 193.54.84.120 netmask 255.255.255.0 route add 127.0.0.1 lo route add 193.54.84.0 eth0 route add -net 0.0.0.0 gw 193.54.84.100 eth0 pppd local 193.54.84.121:193.54.84.122 /dev/ttyS1 115200 nocrtscts noauth proxyarp on PC1 client side : pppd -detach debug local noipdefault defaultroute noauth nocrtscts /dev/ttyS0 115200 PC1 <--PPP--> ARM board <--Ethernet--> LAN & PC2 and I do the following ipv4 settings after mounting /proc echo "1" > /proc/sys/net/ipv4/ip_forward echo "1" > /proc/sys/net/ipv4/conf/*/forwarding echo "2" > /proc/sys/net/ipv4/conf/*/rp_filter echo "1" > /proc/sys/net/ipv4/conf/*/accept_source_route echo "1" > /proc/sys/net/ipv4/conf/*/secure_redirects echo "1" > /proc/sys/net/ipv4/conf/*/proxy_arp echo "1" > /proc/sys/net/ipv4/conf/*/send_redirects echo "0" > /proc/sys/net/ipv4/conf/*/accept_redirects the problem is that PC1 and PC2 can't ping themselves so I tried to arranges the nat table with iptables to do postrouting and masquerading but I get this error: / # iptables -t nat -I POSTROUTING -o ppp0 -j MASQUERADE iptables: Target problem I'm sure Masquerade target option is compiled in the kernel Thanks a lot for any help Happy new year Mathieu Picard _______________________________________________ http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm Please visit the above address for information on this list.
