Never heard of that. Switches and hubs are Layer 1+2 devices (except
you have a Layer 3 switch) so they don't care about IP and consequently
not about routing.
The hosts connected to them are not supposed to "see" switches or
routers and should not care about the Layer 2 topology.

Is s1 the Proxy or gateway or both?
What sort of machine is s1 anyway?
Where is your LAN connected to the internet, through s1?

Does it work if s2 is off?
please specify the setup of the hosts (DHCP?, gateway-address, network-
address)

No, routers are not automatically determined in IPv4, they must be
specified.

What documentation did you read before posting here? Probably you
should read some basics on IP networking...
This one is good:
