You need to disable firewalld and install iptables, if you really want use old way: https://www.certdepot.net/rhel7-disable-firewalld-use-iptables/ Firewalld is preferred way.

I have a server whit 2 interfaces of network, where eth0 is the interfaces connetc to internet and eth1 to the internal network.

Hello listmates, It's been a few years since I've set up a router... and for some reason I seem to be getting hung up on this one. Does anybody have a sample iptables config file that would incorporate NAT and forwarding for a simple router? Thanks. Boris.

Hi all, I'm observing an issue that as soon as libvirt starts, UPD broadcasts going through physical network (and unrelated to any virtualization) get broken. Specifically, windows neighbourhood browsing through samba's nmbd starts suffering badly (Samba is running on this same box). At the moment I'm running a quite outdated version 1.2.9 of libvirt, but other than this issue,

Hello! Sorry if this question is already asked, but I not finding answer for it... I have server with CentOS 6.4, later it will be router for home network. When I tried tune iptables I have error: [root at gateway sysconfig]# iptables -t NAT -A POSTROUTING -o eth0 -j MASQUERADE iptables v1.4.7: can't initialize iptables table `NAT': Table does not exist (do you need to insmod?)

Hi, I am an experienced libvirt user on Fedora versions from F15 to F17. I have developped scripts to route trafic from outside on multiple interfaces/multiples IPs to multiple VMs, and back to affect each VM the required external IP address. I have servers with more than hundreds external IPs, and up to 4 VMs, each of them route trafic on different external IPs. I have servers with Fedora

Hi, I am trying to set up a linux box to act as a router for my college. There are two different types of users; students and conference guests, and they have IPs statically assigned by DHCP, from separate ranges (but they are on the same subnet). The students go out onto an academic connection (via eth0), and conference guests go out on an ADSL line (via eth3). eth1 and eth2 are configured for

Hi, I just migrated my office's server from Slackware64 14.1 to CentOS 7. So far everything's running fine, I just have a few minor details to work out.
