Hi guys thanks alot for your input on this.
@Dawid: I really appriciate your input / correction on/of our configuration as I already assumed that it isn't proper (at all)
Finally I came to apply your changes (or trying so).
One question to it:
1) how do I make it a gigabit interface? with changing to GE instead of FE? somebody told this doesn't mean anything, tho. The SRX itsself does have Gigabit interfaces as our Switches have.
But to the input on the MFPs internet connection I don't agree as I did put the correct (local DNS) server by hand - The device has a static IP, see configuration attached.
Also I corrected the DNS setting to the DHCP on the SRX and put the MFP on auto, but it was the same.
Somebody got another idea, according to the attached settings in the screenshot and the updated configuration?
Thanks alot.
Best, Thore
