----------------------------------------
Summary: In Virtual Router Port Forwarding Service, the connection
is not established when client on the same private network
Key: CLOUDSTACK-4535
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4535
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Virtual Router
Affects Versions: 4.1.0, 4.0.2, 4.0.1, 4.0.0, pre-4.0.0, 4.1.1
Environment: cs4.1.1
Reporter: sie,chih-wei
Priority: Minor
Fix For: Future, 4.2.1
When a client on the same internal network as the Port Forwarding requests a
connection to the service's public IP address & port , the connection breaks.
EX : Port Forwarding for TCP Public_IP:1234 to Private_IP:22
a client(in private network) do => $ssh root@Public_IP -p 1234 => $ ...time out
...
Soulation : In Virtual Router do
$ sudo iptables -t nat -D POSTROUTING -s Private_CIDR -p tcp --dport
1234(public port) -d Private_IP -j SNAT -o eth0 --to-source
$ sudo iptables -t nat -I POSTROUTING -s Private_CIDR -p tcp --dport 22(private
port) -d Private_IP -j SNAT -o eth0 --to-source
https://github.com/apache/cloudstack/blob/master/patches/systemvm/debian/config/root/firewall.sh
74 : (sudo iptables -t nat $op POSTROUTING -s $vrGuestIPNetwork -p $prot
--dport ***$port*** -d $guestVmIp -j SNAT -o eth0 --to-source $vrGuestIP &>>
$OUTFILE || [ "$op" == "-D" ])
have to change ?? =>
(sudo iptables -t nat $op POSTROUTING -s $vrGuestIPNetwork -p $prot --dport
***$guestPort*** -d $guestVmIp -j SNAT -o eth0 --to-source $vrGuestIP &>>
$OUTFILE || [ "$op" == "-D" ])
Thanks.
