port-forwarding

Hi there, I have two ISP providers and 2 routers, both connected into same net 10.20.0.0/24. FreeBSD machine also connected into same network having IP: 10.20.0.10/24, defaultrouter set to 10.20.0.1. How is it possible to forward port, say tcp:22, from both of the routers to the FreeBSD...

I am trying to find out if it is possible to redirect the traffic of several Android systems on my WLAN to specific internal hosts using IPFW. It seems Android hardcodes specific NTP servers and does not honor the "ntp-servers" DHCP option, meaning I have to allow NTP traffic outbound for these...

Hi everyone! What would be the bare minimum pf.conf I would need to block everything and forward any web requests on port 80 to a service running on *:8080? I've had a hunt through the forum but there doesn't seem to be an answer I can get working on my machine.

Hi devs ! I had an idea about how can I reduce my costings but now I need someone who help me translating my idea into PF/IPFW rules. I would like to buy a cheap dedicated server unprotected against DDoS and a VPS protected anti-DDoS. I would like to host on dedicated server few games (udp...

So here's my scenario. * I have a home server (HostB) which is completely within my control. * I have an off-site machine that can potentially be physically accessed by other people I don't trust (HostA). I want to do off-site backups (encrypted of course) via `duplicity` from HostB to...

What would be the easiest way to provide access to the "End devices" on the picture? I need accessing just a few TCP/IP ports. I can use SSH port forwarding, maybe using security/autossh to make it persistent (in pfSense?). Would it be reliable? A fully functional VPN maybe an overkill for this...

Hello, i'm trying to forward a range of ports via ipfw, as the man states the syntax should be: With the TCP and UDP protocols, optional ports may be specified as: {port|port-port|port:mask}[,port[,...]] So i've set the following rule: add 018500...

Hello everyone! I have few network services running in jailed configuration on a server, and I use ipfw to protect the server against possible attacks, and to provide its local clients with access to internet. The goal I want to achieve is redirection of some ports of jailed services to the...

I've already port forwarded from Port 22 to be able to ssh into my server from anywhere, which works. Is this sufficient for a web server or would I also need to Port forward from Port 80 for a web server?

I have FreeBSD 11 on a server where I've installed OpenVPN and I need to setup VPN properly to be able to put internet traffic through it. I can't connect to the internet anymore from my local computer after I've established a connection with my server via VPN. I guess the issue is port...
