  1. Windows Firewall Equivalent IPTABLES MANGLE rules


    Are there firewall rules for Windows 10 or Windows Server that are equivalent to Linux iptables mangle rules?

    Linux iptables mangle rules can combine source IP, destination IP, protocol, tcp/udp port number to set "mangling" rules for TOS, TTL, MARK, TCPMSS, etc. in a single command.

    Here are examples of iptables mangle rules:

    iptables -t mangle -A FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --set-mss 1452

    iptables -t mangle -A POSTROUTING -d xxx.xxx.xxx.xxx -p tcp --sport 80 -j TTL --ttl-set 4-t = table name

    -A = append

    -p = protocol --sport = source port, --tcp-flags xxx,xxx xxx

    -j = jump target TTL = Time to Live of the packet

    -d = destination


    Is there a way to set the same rules using netsh in powershell?

    :)

    Windows Firewall: Doesn't show blocking rules

    Hello!

    Today I've blocked all connections of a program by creating a outbound rule in Windows Firewall. However, I now wish to remove it. The problem: I can't find that newly created rule anywhere in the list. The rule does take an effect, since deactivating the
    Firewall lets the program run properly. I can only see rules in the list that "allow" stuff, but not those who block things.

    What I have tried so far:

    - All filters set to "Show all" within the Firewall

    - Created the same rule again, doesn't show up

    - Created a rule that allows the program, shows up

    Any solutions?
