First, a disclosure: This is my first Cisco device ever. Only ever used dumb hubs/switches and computers before.
We need to use an ASA 5505 to route UDP traffic from one (otherwise air-gapped) private network (192.168.3.x, inside) to another (otherwise air-gapped) network (10.10.10.x, outside). Each network currently has < 5 machines connected by a simple unmanaged switch. The 5505 will have its one outside port connected to the outside switch and its one inside port connected to the inside switch. Traffic is only allowed to flow from inside to outside not the reverse, hence UDP.
I've managed to get it to work for ONE machine on the outside, by setting that machine's address as the gateway. However, it is NOT actually a gateway, it is just a Windows desktop, so this will not work for my actual requirements. But I cannot figure out how to have the firewall just route all traffic received from the inside to the outside network. It is probably quite simple, but it escapes me.
Oh, we've not yet been able to get anything to connect via telnet or SSH to the 5505, but we (barely) managed to get the web/java interface to work from a Windows Embedded Standard 7 desktop (one of the inside machines). Apologies in advance if this is an inappropriate question here.
My running-config.cfg values (from a backup made by the GUI) are:

I hope that is useful. Thanks for looking at this.
