I running on Solaris 10 platform.

Before I enable IPF, I able to ping and traceroute to yahoo.com

After I enabled the IPf, I could not ping nor traceroute to yahoo.com However when I ping to IP (one of yahoo resolved IP) directly, it gives me response.

It seem to be that IPF block the DNS resolvability.

How could I solve it?


Add a firewall rule to allow UDP and TCP traffic on port 53.


Add the pass out rule: pass out quick from any to any keep state
