Hi, I am trying to reach a Raspberry Pi on my physical LAN (192.168.10.132), via OpenVPN, from the internet. The Internet host is 154.77.x.x. This is also the OpenVPN router, 10.8.0.1. The Pi is on 10.8.0.203. I am trying to reach port 3000 from the internet. >From the CentOS 7 server, I can access the Pi over OpenVPN: root at ns1:[~]$ telnet 10.8.0.203 3000 Trying 10.8.0.203...

Here is my nat.sh script just in case someone wants it.. (comments r in spanish.. and not right) Thanks in advance, #!/bin/sh echo "AthoS LaN Generando

I'm having some port forwarding issues issues with iptables. We are using iptables as a firewall with 2 nics and on ip alias. I'm trying to port forward on the alias ip eth0 = 65.x.x.1 eth0:1 = 65.x.x.2 eth1 = 192.168.x.x I'm wanting to forward certain ports(80,5071...etc) that makes request on eth0:1 IP 65.x.x.2 to forward to internal IP 192.168.x.x. I have setup the following rules

I know that I have asked this before of the list. However we just changed ISP and ip's and I'm having this issue again. I have a linux firewall using iptables with the following config eth0 = WAN 1 eth1 = LAN 1 eth2 = WAN 2 I'm trying to forward all traffic that makes a request from eth2 to an internal IP on eth1. These are the folloing rules that I have set up. iptables -t nat -A

I am running Xen on a RHEL4 dom0 and have two RHEL4 domU''s. The domU''s are both running Oracle 10g R2 database. I want to connect to these databases from another computer. Xen is set up with NAT network and all dom''s have access to the internet and they can ping eachother so the network is up and running. My problem is that I cannot connect to the different oracle

Thanks for the reply! output: net.ipv4.ip_forward = 1 What do you mean "The out:any and" Anywhere else I can look as to why the connection isn't going? Do I need some kind of listener at that port on the host? I'm not even seeing the packet count on the prerouting chain increase when the connection attempts are made.

I suppose a few questions pop up on this list about access Samba through a firewall. ?I have been very successful running Samba through a firewall, until today. ?I hit a stumbling block. I have a Linux Firewall with the public IP Address of 134.x.x.140 <it is not the exact ip address, but close>. ?I am using NAT and port forwarding to send traffic destined for 137, 138,139, and 445 for BOTH

Hi all, I have 2 ISPs on a Linux router and a local network with one Linux server and many windows. The local network is masqueraded. I want to give access to port 25 and 80 of my server from any incoming request (i.e. from my 2 ISP). I have made a DNAT translation, witch work but the outgoing answers are not routed correctly. Of course, the de-SNAT process is done before the routing process. So

Easy question here: I have a test network that looks like this (apologies for my lack of ascii skills): [hostc]---------------[Firewall]192.168.42.1 (EXTIF: eth0) /10.0.0.1 (INTIF: eth1) 192.168.42.10 (wan) |(lan) | +-------------[hosta] 10.0.0.10 (port 4242) | +-------------[hostb]

I have a simple requirement/test I'm trying to perform, but having difficulty. I have a system with 2 interfaces, BoxA: eth0? 172.26.50.102 eth1? 192.101.77.62 My goal is to have a tcp port built on BoxA such that hosts on the 192.101.77.0/24 network can reach a port on a different box on the 172.26.0.0/16 network. The target system is 172.26.10.120?? tcp/22 The port I wish to build is

Hi, does anyone remember the rules for port forwarding ? the followings does not work: iptables -A FORWARD -i eth0 -o eth1 -p tcp ?dport 80 -j ACCEPT iptables -A PREROUTING -t nat -p tcp -i eth0 ?dport 80 -j DNAT ?to 192.168.20.1:80 thx lewis
