What you're most likely running into is the DHCP ttl limitation. While it's not often a problem, the SRX sends out a DHCP request with a TTL of 1.
http://forums.juniper.net/t5/SRX-Services-Gateway/SRX-DHCP-client-sends-discover-request-with-TTL-1/td-p/99180 I've seen this in the past, and while rare it does happen every now and again depending on the ISP. As far as I know there hasn't been an feature to tweak the TTL for dhcp discover requests. I hope this helps, -Tim Eberhard On Mon, May 28, 2012 at 5:29 PM, Aaron Dewell <aaron.dew...@gmail.com> wrote: > > Hi all, > > I've been having a problem with an SRX210 connected to a Wildblue satellite > modem (Surfbeam 2 if it matters).
