Debian Routing scripts / Unix/Linux Professional needed

Hello, I need UNIX/linux admin for part time job. Sometimes I need to do something on our servers. On hourly basis. First job to test you will be: Script ./set_routing IP_FROM IP_TO IP_FROM - IP in VPN network connected to server, for example [login to view URL] IP_TO - Other IP, it could be: 1. External Server IP ([login to view URL],[login to view URL],[login to view URL]) 2. Other VPN Servers connected to this server ([login to view URL], [login to view URL]) Traffic should go for example: [login to view URL] --(VPN)---> SERVER -> External IP 72.12.23.12->INET [login to view URL] --(VPN)---> SERVER -> External IP 72.12.23.13->INET [login to view URL] --(VPN)---> SERVER -> VPN2 10.10.0.1->INET Give me the script and it's price.
