Hello I have a TL-ER5120 balancer I have configured two Telmex Modems nn ports 1 and 2 (192.168.3.254, 192.168.4.254) of the WANY also the dedicated port with Lan 192.168.1.1The domains that I have are domain1.sytes.net for the modem 192.168.3.254 dominio2.sytes.net for the 192.168.4.254 modem The balance does it well for the machines that navigate but in the domains it does not workIn the modem, enable the port forwardin and point to the blanaceador ports 80,8080 in the 192.168.3.254 segment and 80 in the 192.168.4.254 segment. Create three groupsNAS1 for an ip 192.168.1.2NAS2 for two ip 192.168.1.3,192.168.4Group for the internal network of ip 100 to 105Then in the option of avanced-> virtual server I wrote two groups for the web servers. One is called demo for the IPs of the group NAS 2 and it indicates the output in the lan wan 1 The other calls it the demo 2 for the ip's of the group NAS1 and I indicated the wan 2But do not let me enter the port, delete the previous onesAlready configure machine by machine for exampleName: demointerface: wan1External Port: 80-80Internal port: 80-80protocol: tcp-ipInternal server 192.168.1.2Name: demo2interface: wan2External Port: 8080-8080Internal port: 80-40protocol: tcp-ipInternal server 192.168.1.3Obio in each modem opened the respective ports but the balancer is lost do not answer the services, but if I configure the modems with port forwarding they answer but it is not the case attached a diagram to see if someone from the forum can give me tipsThe firmware version is V2 for the TL-ER5120
