    Asus Merlin - iptables command (not working?)

    Thanks Colin! I followed your syntax to the letter - changed 192.168.50.10 to my email server 10.0.253.4 and tried it... No Joy...I think what I (maybe?) learning is that...when you use AsusMerlin Browser Interface and Port Forward TCP/25 to 10.0.253.4...that (web browser Asus forwarding) takes...

    Merlin - How to log and review deliberately dropped IP Packets on WAN

    Merlin - helps protected my email server on (LAN) interface. Merlin does this by running a Bash script that deliberately drops (inbound) IP packets on the WAN Interface (read: from Internet).

    WAN Connection Reporting (TCP/UDP inbound) to Router from Internet

    Thanks for your reply...however it's NOT 100% accurate. In order for that to be TRUE a user would have to proactively SET the Asus Firewall Settings to: 1 - enable firewall 2 - enable DoS protection 3 - don't respond to ICMP (ping) request to the WAN port from the Internet. See attached JPG for...
