Different IP ranges

Hello all, I'm having an issue adding different IP address ranges to my dedicated cPanel server and am currently migrating 400+ users to our first cPanel server and then will be adding a second dedicated cPanel server for the others. Beforehand I used addresses like the following to setup my primary domain and nameservers: XXX.XXX.123.45 XXX.XXX.123.46 Well that was all fine and good, then I went on to add a account and assigned that account its own IP, all our accounts have dedicated IP addresses, all on the same subnet mask but in different ranges, however the first 2 octets are always the same but they have different gateways for example 89.98.123.45 -> 89.98.123.1 89.98.135.46 -> 89.98.135.46 when adding another account It appears I must ensure I go with the lowest range first or else the addresses will not route properly. for example I added first 89.98.123.49 and it worked without issue, then I added 89.98.135.50 and it worked fine as well, however then I go back to add 89.98.123.51 and it will not route from outside the network at all. What is interesting about this is that I can get to the IP from anywhere on that same x.x.123.x network even the same server, but not from outside that network. I cannot ping from that interface outside the network either, but I can ping from within it ie ping from 89.98.123.51 to 89.98.123.106. However, if i remove the 89.98.135.50 (example ip) and then add 89.98.123.51 assign it to account etc, then readd 89.98.135.50 everything works fine. I am wondering if there is somewhere I can add the gatway in for these interfaces because they do not create standard config files in /etc/sysconfig/network-scripts/ so that I can route these properly because it seems that they are not using the correct gateway. However I have 4 NICs on this machine and if I must set them all to different ranges I could also do that if needed. Thanks for taking the time to read!
