Vyatta

Building A Router/firewall -- Vyatta? Untangle? Endian?

I would like to thank in advance to anyone who shares his knowledge or experience here.

I am trying to find a firewall with some routing capability. Since I expect to have Gbps transfer in the near future, I don't think I can find a solid commercial hardware firewall within my low budget. That's why I am looking at software products.

I would need firewall functions(ability to prevent DDoS attacks is desirable) and basic routing functions (dynamic routing and BGP is desirable but not necessary at the moment).

Stage 1 environment:
20Mbps from provider P;
100Mbps from provider C;
35 servers for budget dedicated, mainly web servers;

*I have a question in mind that, can I have my network setup that incoming from both provider P and C but outgoing through C only? Is static routing able to do that?

Expected stage 2 environment:
40 ~ 60Mbps from provider P;
100 ~ 200 Mbps from provider C;
70 ~150 servers, mainly web servers;

Currently I am looking at Vyatta, Untangle and Endian. Can someone give some comments on these software or any others that might be suitable for me?
