I have an isp with dynamic ip and i need to remote a pc quite frequently, however i only have x86 rb and since ipcloud isnt supported by x86,
Is it possible to use secondary x64 box to forward the ip public value to the x86 box?
How would they communicate then? Whats the position of x64 in x86 rb?

Thanks

That's just different architectures RB will be running on. Traffic on network is independent of that.
