Wrong Routingtable

Dear Retool-Community,

i deployed onPrem/selfhosted Retool on Docker.
The IP-Adresse of the Machine is 172.16.0.XX
In the company, we have several location, each location has its own range.
First is 172.16..., 2nd is 172.17... , 3rd is 172.17, 4th is 172.18 etc...

The "problem?" now, i can only access retool and docker etc from ips that starts with 172.16...
If i switch e.g to a server from the 2nd or 3rd location, i cant access it. Either port for icmp, ssh, 443 or 80 works. From an client with the ip 172.16... i can use all those protocols etc.

in the route table of the ubuntu-machine i get the following:
@sv-lx-retool-01:~$ route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface 172.16.XXXX UG 0 0 0 eth0 U 0 0 0 eth0 U 0 0 0 docker0 U 0 0 0 br-c8accbd3f286 U 0 0 0 br-0a846495f227 U 0 0 0 br-f97e0574b523 U 0 0 0 br-d471916ed886

My Guess is that retool created those entrys and destinations based on its own ip (172.16) and then upwards for every container.

Does somebody know what i need to change to get it working from the other locations?
