I'm looking for a software helping me to solve a problem I have in my office network. I have a laptop connected via LAN to local servers, webfarm servers, webfarm and internet. In this network I am behind a proxy that blocks some ports and IPS and all the time I have to ask to open them temporary. In our office we also have a WIFI router connected to internet without any restriction. So if I want I can disconnect the LAN, connect WIFI and go wherever I want.
What I'm looking for is a way (or better a software) that let me to be connected with both interface (LAN and WAN) at the same time. By default I would use the LAN connection. With the software I would like to add filters by IP or domain or port that let me choose some kind of services to use the WAN connection instead.
So for example if I want to go to Google.it it would use the LAN. But I can add a filter for 8080 port and all the connection to 8080 services would use the WAN. I would use it mainly with web browsers but I would like to use it also for other software like ftp or custom software.
To me it looks like a virtual network card. All the connection are handled by this virtual card that send traffic to LAN or WAN depending on filters. I tried looking around but no luck.
Do you have any idea on how I can do something like that?
