Repeater

UltraVNC Repeater

The Repeater acts like a proxy, sitting in the middle between the server and viewer. All data for the session is passed through the Repeater meaning that the viewer and server can both be behind a NAT firewall, without having to worry about forwarding ports or anything else (providing the Repeater is visible to both viewer and server).

WARNING: In MODE I, the Repeater works like a proxy. If you don't limit the destination and or ports your Repeater can be used to connect to all IP adresses and all ports that can be reached from the Repeater.


You need to restrict the IP addreses and ports to prevent unwanted access.

Default VNC ports 5901, 5500
Default Webgui:80
Default user: admin
Default password: adminadmi2

update 1400 security fix for webgui

The keepalive option can only be activated if all winvnc are >= version 1201
The older vnc server don't understand the keepalive repeater to server message.

The message is used to prevent that timeouts close the connection.

Don't forget to restrict mode1 access in theuvncrepeater.ini from the linux port.

[mode1]
;0=All
allowedmode1serverport = 0

;0=Allow connections to all server addressess,
;1=Require that server address (or range of addresses) is listed in
;srvListAllow[0]...srvListAllow[SERVERS_LIST_SIZE-1]
requirelistedserver = 0

;List of allowed server addresses / ranges
;Ranges can be defined by setting corresponding number to 0, e.g.
10.0.0.0 allows all addresses 10.x.x.x
;Address 255.255.255.255 (default) does not allow any connections
;Address 0.0.0.0 allows all connections
;Only IP addresses can be used here, not DNS names
;There can be max SERVERS_LIST_SIZE (default 50) srvListAllow lines
srvListAllow0 = 10.0.0.0        ;Allow network 10.x.x.x
srvListAllow1 = 192.168.0.0     ;Allow network 192.168.x.x

;List of denied server addresses / ranges
;Ranges can be defined by setting corresponding number to 0, e.g.
10.0.0.0 denies all addresses 10.x.x.x
;Address 255.255.255.255 (default) does not deny any connections
;Address 0.0.0.0 denies all connections
;Only IP addresses can be used here, not DNS names
;If addresss/range is both allowed and denied, it will be denied (deny
is stronger)
;There can be max SERVERS_LIST_SIZE (default 50) srvListDeny lines
srvListDeny0 = 10.0.0.0         ;Deny network 10.x.x.x
srvListDeny1 = 192.168.2.22     ;Deny host 192.168.2.22
