Firewall blocking Innerspace/ISBoxer

[Wokomehee]

I decided to try out Innerspace/ISBoxer, but having some probs with the setup for 2 pc's. Been reading on forums and tried different things, but my firewall keep blocking Innerspace.

My main pc Run Vista, and slave Winxp. When i disable firewall on slave pc, they connect and all 5 clients start. But when enabling firewall on slave again, the 2 clients on slave pc fail to start.

I have enabled connection in firewall on both pc's, for both Innerspace and ISBoxer toolkit, and i am running Innerspace as administrator on Vista pc. On "configuration" in Innerspace i have enabled connection, and both pc's have their unique names.

Any suggestions what i do wrong, or what i can try please? Thanks in advance =)
