Allow TFTP traffic Through IPCOP Firewall

It is weired that IPCOP block the tftp traffic from external server to internal. In order to work properly we have to add rule manually in the /etc/rc.d/

imran@imran-laptop:~$ ssh root@192.168.0.1 -p 222
root@10.47.0.1's password:
Last login: Mon Jun 8 16:21:12 2009 from imran-laptop.owera.com
root@firewall:~ # nano /etc/rc.d/rc.network


## add following for TFTP traffic

modprobe ip_conntrack_tftp
modprobe ip_nat_tftp



Reboot the Firewall to take effect or enter the above command in command line.
