unable to connect to umurmur from WAN

[matrycy]

Hi,
I'm not able to connect to umurmur on my RT-AC86u running Asus Merlin 386.4 from WAN. Deamon is running, connecting from LAN without issues. Port 64738 is open:
admin@RT-AC86U-DF50:/tmp/home/root# iptables -L INPUT -v -n | grep 64738
0 0 ACCEPT tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:64738
0 0 ACCEPT udp -- * * 0.0.0.0/0 0.0.0.0/0 udp dpt:64738

Iptables -L
ACCEPT tcp -- anywhere anywhere tcp dpt:64738
ACCEPT udp -- anywhere anywhere udp dpt:64738

What am I missing?

Make sure you inserted your iptables rule rather than appending it because the last default rule is a drop.

That worked. Thank you!

It looks like the rule is removed from iptables after some time. How to prevent it?

You need to create a firewall-start user script.
