Michael, Could you add three (3) more port forwards from the outside world to ServerA (192.168.0.3) please? 8881 -> 192.168.0.3:80 (mapserver) 8882 -> 192.168.0.3:8080 (geoserver) 8883 -> 192.168.0.3:8399 (arcgisserver) We're going to use those so we can put up equivalent WMS urls on the wiki and compares styles on the servers. Thanks, Paul
