VPN overlapping with network that provides access to internet

it flag

I have computer which is connected to Network A with ip range 10.0.0.0/24. This network provides access to internet and that's the only thing I need from Network A.

My comporate VPN (Network B) using using ip range 10.0.0.0/8.

I was thinking about somehow setting up nat and route tables to translate Network B to 11.0.0.0/8. Is there a chance to do that?

A slightly longer explanation for solving that here: https://www.practicalnetworking.net/stand-alone/vpn-overlapping-networks/ - but don't use "random" publicly routable IP-addresses such as 11.0.0.0/8 but one of the other private use ranges https://en.wikipedia.org/wiki/Private_network

Implement IPv6 and solve overlapping address space problems forever.

When the internet access via A is over its own unique IPv6 prefix, for example 2001:db8:45b2::/48, it no longer conflicts.

IPv4 internet access is still a problem, VPN net B is claiming 1918 space in use by A. Network A could be IPv6 only and provide IPv4 as a service, like a NAT64. Or, A's NAT could be renumbered to space that is not in 10.0.0.0/8. Either of these avoids an additional NAT of 1918 space.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
