Merging site feeds

I have two sites at the same location. They both use the same router but have different IP addresses. Is it possible to merge both feeds to report all aircraft on one site feed rather than both on an individual basis? I tried changing the Unique Identifier on the second site to the UI of the first site and that just prevented the second site from reporting. I reverted the Identifier to the original and the site is now receiving again.


Timestamps from the samples of the two receivers will be different and MLAT will stop working correctly (or even be deactivated completely).
Also, the software that sends the samples to FA website, when receives identical samples on input, it just discards them before sending.

ModeSMixer2 is versatile console application for combining and rebroadcasting feeds with Mode-S data in a variety of formats.
