Split access on a single interface
...his box and a Linux solution is that a LinkProof
can be installed without changing the IP addressing.
Basically, both ISP routers are connected to a shared hub, together with the
LinkProof and the box connecting the internal network (Firewall, Router...)
The LinkProof is then doing what they call SmartNAT (for outbound only.
Inbound is handled by DNS)
My major problem is the NATting decision for outgoing connections:
On Linux, I have two default routes in a routing table, and depending on the
routing decision, I can match the OUTGOING INTERFACE (-o ethX) to take a NAT
decision in the NAT POSTROUTI...
