Network service filter causing problems?

[Mikeyy]

Hello all.

My setup:
Asus N66U + .55 Merlin
I have VPN client with policy routing for 2 LAN ip's.
Also, I have script from this thread to enable port forwarding from WAN to those 2 VPN devices. Port forwarding goes over standard internet.

Everything was working last night, but then I way playing with router and tried "Network service filter" to see if I can block all LAN traffic from going to one IP. Didn't enter anything into other fields, I just filled destination IP. Later I tested with ports, but since nothing worked, I just disabled it.

Problem:
My port forwarding to VPN devices isn't working any more. Restarted router, NSF is off, but it's not working.
Checked log and last line was:

Oct 31 17:13:43 kernel: nf_ct_ras: decoding error: out of range

Any ideas why it suddenly doesn't work? Does this line has anything to do with it?

Aparently, for whatever reason, messing with NSF turned off executing JFFS scripts.
Admin - System - Enable JFFS custom scripts and configs "YES" fixed it.

EDIT: Not really sure what's happening here. Some reboots it works, others doesn't. Same script, same setup. How can I find out why port forwarding trough vpn isn't working after some reboots?
