@MotherFogger Interesting to hear that it’s all working fine when you stay within the ESX VM environment. As well the NFS config (exports) looks good to me.
What’s in between the client and the FOG server? Some kind of router / level 3-7 switch that might interfere here? Yes, please take another packet dump with the new syntax. Maybe the packet dump file will grow a little bigger then but it’s definitely worth it. In case it grows to 5 MB and more you might upload the file somewhere and send me the link via mail.
