My laptop is connecting via mobile broadband and have a global IP. $ ifconfig ppp0 Link encap:Point-to-Point Protocol inet addr:120.166.xx.xxx P-t-P:10.64.64.64 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:4245 errors:0 dropped:0 overruns:0 frame:0 TX packets:4914 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:1253230 (1.1 MiB) TX bytes:948317 (926.0 KiB) > -deleted- > > How can one tell if one is behind a router that uses NAT? > What is your local host's IP address? > If your host's IP address is in the range, listed by rfc 1918, > http://www.rfc-editor.org/rfc/rfc1918.txt > 192.168.0.0 - 192.168.255.255, 172.16.0.0 - 172.31.255.255, > or 10.0.0.0 - 10.255.255.255, you are behind a router running NAT. If I switch my connection to another provider, so that I have my own router, and the IP of the nodes are no longer global, (IP range 192.168.1. 1 etc), I can ssh between them, as well as to outside. regards, AA -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
