Toothache is merely a symptom of being sick. It can cause sore throat, swelling of the gums, neck glands and muscle pains. There is a dull or sharp pain on the head or jaw bones. Toothache cause by abscess formation can spread to oral parts of the mouth. Ulcers can break open and release more bacteria.
iptables is a user-space application program that allows a system administrator to configure the tables provided by the Linux kernel firewall (implemented as different Netfilter modules) and the chains and rules it stores. but since iptables is more like a service rather than an essential binary, the preferred location remains. . The term iptables is also commonly used to inclusively refer to the kernel-level components.
If in the meantime anyone here is good with iptables, below is the *NAT* table for Router1 and Router2. These tables need a rule to allow all WAN originating traffic to reach the LAN network. Maybe Tomato has a way to do this within the UI, but I haven't spotted it yetâ¦ (and btw, the answer isn't disabling NAT =:)).
