IR Blaster not Broadlink

Hi fellow folks!
I’m trying to automate my office but I’m facing a problem. My cisco routers are not compatible with my Broadlink devices (which worked at my house before with Tenda mesh routers). Tried the same devices at my house again and they work flawlesly but my office they won’t (it’s a shared building so it’s not possible to change the network).

My questions is: is there any device that could help controlling IR devices among Broadlink devices? (tried RM4 Pro and RM4 Mini)
