Internet Routing with BIRD

I am testing BIRD to put into production to replace several VPN appliances I am using to route to my AWS site. I've never used BIRD before so please forgive ignorance/ If I put a test windows machine behind this routing server I am able to route to my amazon nets and my other networks locally, however I cannot route to the internet.

I can see in my BIRD routing tables an entry for 0.0.0.0/0

bird> show route
0.0.0.0/0          via 204.244.x.x on eth1 [kernel1 15:03] * (10)
172.30.0.176/28    dev eth0 [static1 15:07] ! (200)
192.168.120.0/23   via 204.244.x.x on eth1 [R1 15:03 from 10.0.0.241] * (100/?) [AS7224i]
172.31.5.80/29     dev eth0 [static1 15:07] ! (200)

Would this be causing issues with routing out to the internet from a server in the 172.30.0.176/28 network that is using the router as its default gateway? If so how can I change the routing so that BIRD doesn't try to route internet traffic and only traffic for the internal networks?

Below is my configurations:

Client machine: IP 172.30.0.188/28 gateway 172.30.0.190

BIRD configuration:

# Configure logging
log syslog all;
log "/var/log/bird.log" all;
log stderr all;

# Override router ID
#router id 10.0.0.245;

function avoid_martians()
prefix set martians;
{
        martians = [ 169.254.0.0/16+, 224.0.0.0/4+, 240.0.0.0/4+, 0.0.0.0/32-, 0.0.0.0/0{25,32}, 0.0.0.0/0{0,7} ];

        # Avoid RFC1918 networks
        if net ~ martians then return false;
        return true;
}

function avoid_crappy_prefixes()
{
        if net.len < 8 then return false;
        if net.len > 24 then return false;
        return true;
}

filter bgp_out
{
        if net = 192.168.120.0/23 then accept;
        else reject;
}

filter bgp_in {
        if avoid_martians() && avoid_crappy_prefixes() then accept;
        else reject;
}

# Sync bird routing table with kernel
protocol kernel {
        learn;
        persist;
        scan time 20;
        export all;
}

# Include device route (warning, a device route is a /32)
protocol device {
        scan time 10;
}

protocol static {
        route 172.30.0.176/28 via "eth0";
        route 172.31.5.80/29 via "eth0";
}


protocol bgp R1 {
        local as 65200;
        neighbor 10.0.0.241 as 65100;
        multihop;
        import filter bgp_in;
        export filter bgp_out;
