Port forwarding rules don't work after hardware reboot.

Hi all. I setting up NAT with masquerade, and add a firewall->NAT rules for port forwarding (SIP-5060 and rtp 10000-19000)
This work correct, but any time, when I use hardware reboot (reattach power lines) my RB-1100AH, RouterOS don’t forward ports after reboot.
How can I fix it?

You might first port your NAT configuration here so we can see what you are trying to do and maybe suggest changes.

Thanks for the reply,
This is my NAT config:
http://pastebin.com/raw.php?i=qxRgSWUp
mannetic-pptp - pptp interface,
10.6.13.186 - local IP address in ISP network
91.203.. - external IP
After hardware reboot, or Internet disconnection, rules for port 5060 and 9000-19000 don’t work.

This is strange, but RDP port forwarding work after power lost or Internet down/up.

What do you do to resolve the issue currently? The rule still show up in your config after the reboot but just does not work? Is that what you are saying or doe the rule get removed from the config due to the reboot?

One big thing I would suggest is to get your Masquerade rule at the bottom of your rules list, or at least after your SIP rules.
