[Cerowrt-devel] [Bug #445] doesn't load firewall rules under some circumstances

[Ranga Krishnan]

I have seen this happen and others working on the EFF router have 
experienced this somewhat rare but persistent problem of firewall 
rules not loading.

I have seen mention of this problem on OpenWRT mailing lists
as far back as 3 years ago. Looks like the problem is documented
but has not been fixed. 

I am just going to add 

/etc/init.d/firewall restart

in /etc/rc.local to act as a backup until this is properly resolved.
