@Adam with my laptop I can reach the .1 but I can't get any further than that. IP configuration on the MX it's uplink is the same as it was in the laptop The MX is online with WAN2, but I always configure this through the local page in case it goes offline. @PhilipDAth Ok, this is exactly what I thought.. I'll get back in touch with the provider to figure this out. His quick Google skills made him email me to use 1:1 nat.. I'm not sure if they are willing to change their /31 into a /30. This is a ping from the provider his side towards the MX250. Pings are responding and OK But the other way arround it does not work. 1921_rtr1_access_AJD#ping vrf VO-ISP 192.168.99.1 Type escape sequence to abort.
