AT&T has told us they will be willing to route the 198 stuff for us so we don't have a bass-ackward network initilazation that is flaky and potentially slow at best (TCP Data payload over UDP VPN packets). I guess after Shelby showed them what we are having to do they felt sorry for us. This is what a branch office looks like that utilizes the VPN. 251 is the branch IP. root@wpi251:~> route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.199.1 0.0.0.0 255.255.255.255 UH 0 0 0 tun0 192.168.199.0 192.168.199.1 255.255.255.0 UG 0 0 0 tun0 192.168.99.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.251.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 198.46.71.0 192.168.199.1 255.255.255.0 UG 0 0 0 tun0 198.46.71.0 0.0.0.0 255.255.255.0 U 0 0 0 tun0 10.0.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 10.1.0.0 10.0.251.1 255.255.0.0 UG 0 0 0 eth0 127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo root@wpi251:~> ifconfig eth0 Link encap:Ethernet HWaddr 00:30:48:59:AA:32 inet addr:10.0.251.2 Bcast:10.0.255.255 Mask:255.255.0.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1858842 errors:0 dropped:0 overruns:0 frame:0 TX packets:1472756 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1350221231 (1287.6 Mb) TX bytes:287315772 (274.0 Mb) Base address:0x4000 Memory:ed280000-ed2a0000 eth1 Link encap:Ethernet HWaddr 00:30:48:59:AA:33 inet addr:192.168.99.1 Bcast:192.168.99.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1323227 errors:0 dropped:0 overruns:0 frame:0 TX packets:1678541 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:159084023 (151.7 Mb) TX bytes:1220977738 (1164.4 Mb) Base address:0x5000 Memory:ed300000-ed320000 eth1:1 Link encap:Ethernet HWaddr 00:30:48:59:AA:33 inet addr:192.168.251.1 Bcast:192.168.251.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:460951 errors:0 dropped:0 overruns:0 frame:0 TX packets:389413 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:245363054 (233.9 Mb) TX bytes:59053586 (56.3 Mb) Base address:0x5000 Memory:ed300000-ed320000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:293299 errors:0 dropped:0 overruns:0 frame:0 TX packets:293299 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:20591143 (19.6 Mb) TX bytes:20591143 (19.6 Mb) tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:192.168.199.101 P-t-P:192.168.199.1 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:460951 errors:0 dropped:0 overruns:0 frame:0 TX packets:389413 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:245363054 (233.9 Mb) TX bytes:59053586 (56.3 Mb)
