title: Forward Packets with Socat
|
|
---
|
|
|

I've written about relaying TCP traffic using [SSH port forwarding](/blog/sshlocalportforwarding/). Though sometimes you don't require the authenticity and encryption of SSH or want to use another protocol such as UDP. That's where `socat` comes in.
|
|
|
|
The following will listen to TCP traffic on port 8001 and redirect it to TCP localhost:8000
|
|
|
|
```bash
|
|
socat tcp-listen:8001,reuseaddr,fork tcp:localhost:8000
|
|
```
|
|
|
|
This will listen UDP on port 4009 and forward it to UDP localhost:4010
|
|
|
|
```bash
|
|
socat udp-listen:4009,reuseaddr,fork udp:localhost:4010
|
|
``` |
