The last shitshow I worked at insisted on 192.168.x.x for their corporate VPN. I'm not sure what they were smoking, but there was no way in hell I was going to reconfigure my entire home network so I could use their shitty VPN, so I just found another way in. Dumbasses.
For similar reason we also steered away from home router area of 192.168.X.X for our company network stuff.
