mudwfp_proxy Command-Line Options

The mudwfp_proxy process uses Windows Filtering Platform (WFP) to route traffic from specific processes through Mudfish.

Command-line options

The following options are available:

• -b <pattern>

  Defines a rule to apply. The following rules are supported:

  • <procname>|F

    Proxies traffic from the specified process locally. This is typically used to identify the IP addresses and ports a process uses, or to check whether the process works correctly through mudwfp_proxy.

  • <procname>|B|<ip>:<port>

    Forwards traffic from the specified process to the given IP address and port. This corresponds to Basic Mode for Mudfish nodes.

  • <procname>|A|<ip>:<port>|<ip>:<port>

    Forwards traffic from the specified process through two IP addresses and ports. This corresponds to Advanced Mode for Mudfish nodes.

  Set procname to * to apply mudwfp_proxy to all processes that generate traffic.

• -e <procname>

  Excludes the specified process from mudwfp_proxy.

• -E <CIDR>

  Excludes the specified network block from mudwfp_proxy.

• -M <value>

  Sets the maximum MTU, which is used to check packet sizes when forwarding UDP packets.

• -r

  Controls whether mudwfp_proxy logs are written to a file or to stdout.

• -S

  Runs mudwfp_proxy on its own, without other Mudfish programs. It skips initialization of communication with other Mudfish programs.

Examples

• mudwfp_proxy.exe -b "chrome.exe|B|1.2.3.4:8085" -b "firefox.exe|A|1.2.3.4:8085|2.3.4.5:8085"

  Forwards traffic from chrome.exe to IP address 1.2.3.4, port 8085. Traffic from firefox.exe is sent to 1.2.3.4:8085 with the 2.3.4.5:8085 destination information encapsulated in it.

• mudwfp_proxy.exe -b "*|F" -e "firefox.exe" -E "14.63.0.0/16"

  Filters traffic from all processes except firefox.exe, and excludes traffic destined for 14.63.0.0/16.

• mudwfp_proxy.exe -b "firefox.exe|F

  Filters traffic from firefox.exe and proxies it locally. It does not forward the traffic to another node.
