ER605 Port forwarding not Working
Previously i was using TP link Archer C64, C1200, C80 & AX1500 configured as access point to same wired lan and i was able to port forward RDP to a custom port on my Server, able to access it from anywhere (for eg: router lan ip being 192.168.1.1 and port forwarded to 192.168.1.200)
Now due to requirement of multiple Internet for use as primary and backup in case of failure, i have installed ER605 with 3 WANS each being a different IP range
WAN - 192.168.3.1
WAN 1 - 192.168.4.1
WAN 2 - 192.168.5.1
LAN ip range is still the old one as above in range 192.168.1.x
I have already set port forwarding in ER605, and in my broadband routers and also set rule in Firewall - access control to allow incoming connection as per below links
business-forum-topic-573490 & business-forum-topic-516620 & as per user guide for ER605 from TP-link website
i am still unable to access my server PC if i connect internet through my ER605 Device Lan port, and the port 3389 or any custom port are shown as closed but if i connect the Server LAN to my broadband router (Archer C80 or AX1500 or C64), i am able to access my Server using all three different Broadband connection. The port 3389 or any custom port i use is shown open using open port tool from yougetsignal
Same set of Port forwarding rules is set in virtual server in ER605, Archer C80, Archer C64, Archer AC1200, AX1500
kindly help and advise where do i need to check and solve this problem.
PS - i am not using any kind VPN on ER605. all VPN configurations are as default as it came on ER605 as factory default. Not configured anything at all in VPN.
