Reload is completely safe - no traffic will be dropped.Īs mentioned at the start you'll also need to ensure that your web servers are correctly configured to log the X-Forward-For header details:īut as far as configuring the load balancer is concerned, that's it! Did you know, HAProxy can even use the XFF for a stick table?Īn awesome feature of HAProxy is that you can define a stick table (persistence) based on the client source IP contained in the XFF header (or from the PROXY protocol).« 七月文章分類文章分類 Tag 7-mode AIX Backup Blade Brocade browser Burning Cisco CVE CVM DELL Diagnostic ESXi Ethernet Firefox Firmware Fonts Fortinet H3C Hardware Hitachi Vantara HPE Huananzhi Hyper-V IBM Information LAG leno Lenovo License Linux LXCA Mail Management Microsoft Miracast Mobile Monitor Multipath NetApp Network Nutanix P2P Performance Pictures PowerShell PXE RedHat Remote Report Security Server SMB SMB1 Sniffer SSH Storage Switch Symantec TCP Tunnel Type UCS Unattended vCenter vCSA VEEAM VERITAS VMware vRealize vSphere Web WiFi Windows Workstation 熱門文章與頁面︰ Using the WUI option: Cluster Configuration > Layer 7 - Virtual Services click next to the relevant HAProxy Virtual Service and check that the correct options have been enabled Set X-Forward-for Header(enabled by default) and Proxy Protocol as shown below:įinally, reload HAProxy and stunnel to apply the changes using the restart buttons that appear at the top of the screen as shown below: b) Check HAProxy Configuration (optional) When you select the target HAproxy VIP from the drop down list - it will automatically modify HAProxy to accept PROXY protocol AND insert the XFF header.

It looks like Firefox 4.01 tries to switch to http instead of https (and keeping port 9090). You probably have a hard limit of the number. TIMEOUTclose 0 sabnzbd accept 9090 connect 8080 TIMEOUTclose 0-Unfortunately, when using Firefox 4, I can login and check the main page, but i get errors when I try to go to the config page. This enables stunnel to pass the original client IP address to HAProxy. Stunnel is complaining that there are too many open files and is refusing new connections. Note: For more details on the protocol option please refer to this page. To force stunnel to pass the original client IP address the protocol directive in stunnel must be added and set to proxy as shown below: Ĭert = /etc//certs/STunnel.pem This is because stunnel is not transparent by default.

!( By default, in the above example the IP address in the X-Forward-For header reaching the Web Servers is the load balancers own IP address. For more details on enabling this for IIS and Apache web servers, please see IIS and X-Forwarded-For Headers and Apache and X-Forwarded-For Headers.įor more complicated scenarios where SSL termination is also required on the load balancer and the original source IP address is still required, additional steps are needed. One way around this is to enable X-Forward-For headers for HAProxy (the default for appliances) and configure the web servers to track the IP address in this header. By default, the source IP address of the packet reaching the web servers is the IP address of the load balancer and not the IP address of the client. However you can get a way to debug with the 'debug 7', and specifying the log file with 'output ', and realizing that the log file is relative to the chroot.

First for the confused searchers, the forground option in stunnel4 doesnt seem to work. This occurs for example when HAProxy is used in it's default configuration to load balance a number of back-end web servers. Trying to configure stunnel to execute althttpd to execute cgi in general, fossil specifically. When using proxies such as stunnel and HAProxy it's easy to loose track of the client source IP address.
