The only thing you would be using the WAN link for would be to interact with MDT and the target VM over RDP.I’ve been using a number of servers over the years (originally Windows servers) but have decided that they are too resource heavy for my little HP MicroServer especially as I’m using VMware to host them (I like using snapshots in case I make a mistake). If you are developing the image, when you return to work you can just take it back on a USB flash drive, or if you are developing it, do everything remote and test your deployments on a VM that you can discard and start over on. Why not spin up a local mdt/wds server and image locally? In one 6 hr span you could probably copy the source wim file and all of the applications over the lte link and then just work on it locally.

The point is you might need to be researching how to optimize smb over your lte connection and not tftp.Īlso 6hrs is a long time to build a system over lte. I'm speaking from no basis of knowledge other than knowing that the tftp protocol is the slowest of them all and M$ probably would switch over to their preferred transfer protocol as soon as possible. So messing with the tftp block size should only impact wdsmgfw.efi being delivered to the target computer. From there I'm suspecting the MS boot loader uses SMB to transfer the WIM file and not tftp. FWIW: a block size of 1472 is still ~3 times the block size of 512, The other thing you need to research is once the boot loader gets transferred to the target computer, it takes over from the PXE rom (I know that as fact). In my experience a 5GB image took almost 6 hours to complete with WDS/MDT.ĭo you know what your lte block size is? That may also restrict your connection. Any experiences or thoughts on this? And yes, I know imaging is not recommended over a WAN but when you are quarantined at home it has been fun to play with.

Using a TFTP block size of anything bigger than 1500 plus allowing the Variable Windows Extension seems to be the way to go. In my case, I have a WAN plus IPSec over LTE for the PXE boot so their is overhead in the tunnel plus the MTU size is reduced on LTE side. Most switches, unless jumbo frames are enabled, are likely set to 1500 so I don't see a benefit in setting this higher unless you enable the Variable Windows Extension which will allow the client and server to negotiate the block size and probably reduces it to the max MTU of 1500 minus overhead. I have seen where people have suggested setting the max tftp block size to something like 16384 but this in turn will create IP fragmentation which will ultimately lead to more overhead. It appears that the default block size is 512 bytes for TFTP in WDS, which in turn causes more packets and equates to more round trip time. I have been playing around with a couple of things on the tftp side to make the file transfer more efficient. You will get strange actions out of some pxe booting computers if that value is set but you don't have a proxydhcp server running on udp port 4011. Only a proxydhcp server should set that value in its DHCP OFFER to the target computer. That option tells the target computer the response is a proxydhcp response. Once the boot loader has been downloaded then you don't need the pxe boot.
Even something like pfsense running on a VM supplying the dhcp will supply the right boot information to the client to get you started. The other option is to use a different dhcp server to supply the boot information. The ProxyDHCP service is what WDS uses to override any boot settings that might be in dhcp options 66 and 67 on your main campus. If you use a ProxyDHCP service like dnsmasq. There is a way around this but I'm not sure if it will add value.
My bet is that if you look in the ethernet header the IP address of your router is in there. As you said dhcp option 66 is being ignored. Even though it allows you to set dhcp option 66 it sets the router as the next server (bootp) in the ethernet header, and sometimes overrides dhcp option 66 with its address. I have seen this happen with several brands of soho routers.
