I've set up VPN network between office and shop. Everything seems to be ok except for the fact that I can ping simple devices only. For example, we have scales with TCP/IP interface. So, from the office I can ping scales, that are on the shop network. But I cannot ping Linux Pcs there. And vice versa. I can ping even routers, where I set up permissive rules.
I believe, there is some network setting, that makes PCs drop packets from VPN network. Can you please help me find which one?
Office network is 192.168.254.x, shop one is 192.168.1.x.
I think this is because a PC on 192.168.1.0/24 does not accept packets from 192.168.254.0/24 on the PPP interface, which is Internet. Is there any option to allow this?
