Alright how many people are still running some sort of NOS on DOS? Time to move forward folks and use the excellent routing capabilities of Linux. Every time I look at the encap.txt and see stuff like: route addprivate 44.129/16 encap 118.22.1.194 I ask myself why do we still export is this way. I say export it as: ip route add 44.129.0.0/16 via 118.22.1.194 dev tunl0 onlink And let those who still need it the old way learn the pain of conversion. Give them a reason to upgrade/ move forward. </Off my soap box> ---- Quote--- Bart, Don brought up some good points. In addition: - non Linux-kernel routers (e.g. JNOS and TNOS) would not be able to route to you as they would need to be reprogrammed and recompiled (FYI, JNOS and TNOS is the most commonly used AMPR Network OS)
