![]() ![]() Note: MobaXterm is only useful if you are using SSH to connect to NAS systems. You can also use it to create VNC sessions. MobaXterm includes a built-in X11 client, and has the ability to forward X11 from NAS systems back to your local system. Of the firewall of the physical host and not the OpenStack vm.Īs Eric pointed out, the rules you are trying to add with firewalldĪre not getting saved on the physical host (titan08).You can use MobaXterm to connect from your local Windows system to NAS systems via SSH, as an alternative to Cygwin/OpenSSH. In that case, it seems that this is entirely about the configuration OpenStack rpm's or configuration done on the physical host itself Undercloud-0 is where OpenStack is installed. Trying to add firewall rules on the host (titan08) that is hosting a No, this is not correct based on how I interpret the bug. Note that it is known to effect OSP 14 and bellow. It sounds like your problems aren't a problem with your firewall-cmd commands, but something to do with OpenStack?įor reference, I'll post the final response (by James Slagle, presumably this one) on the Bugzilla report you made - just in case it helps someone:Īs suggested by Eric, this issue is related to OSP deployment, thus changing Ssh: connect to host my-host port 222: Connection refused Now, when trying to connect to the guest - from my laptop, via host port 222 - the ssh connection is refused: ssh -l stack my-host -p 222 Ipv4 filter FORWARD 0 -d 0.0.0.0/0 -j ACCEPT Ipv4 filter OUTPUT 0 -d 0.0.0.0/0 -j ACCEPT ![]() Ipv4 filter INPUT 0 -d 0.0.0.0/0 -j ACCEPT # firewall-cmd -permanent -direct -add-rule ipv4 nat PREROUTING 0 -d 0.0.0.0/0 -p tcp -dport 222 -j DNAT -to-destination 172.16.0.2:22 # firewall-cmd -permanent -direct -add-rule ipv4 filter INPUT 0 -d 0.0.0.0/0 -j ACCEPT # firewall-cmd -permanent -direct -add-rule ipv4 filter OUTPUT 0 -d 0.0.0.0/0 -j ACCEPT # firewall-cmd -permanent -direct -add-rule ipv4 filter FORWARD 0 -d 0.0.0.0/0 -j ACCEPT # firewall-cmd -permanent -zone=public -add-masquerade Using firewall-cmd on Host - it will NOT work: # firewall-cmd -permanent -zone=public -add-forward-port=port=222:proto=tcp:toport=22:toaddr=172.16.0.2' ![]() So I'm trying to do the same port forwarding with firewall-cmd. However, iptables are not saved on Host reboot, since firewalld service is running (firewalld is the default in RHEL 7). # iptables -I INPUT -d 0.0.0.0/0 -j ACCEPT # iptables -I FORWARD -d 0.0.0.0/0 -j ACCEPT Using iptables on Host - it will work: # iptables -I OUTPUT -d 0.0.0.0/0 -j ACCEPT Ssh from laptop -> Host with port forwarding in firewall -> Get directly into guest (172.16.0.2, behind host NAT). I'm trying to do an ssh tunnel into a server behind NAT: ![]()
