I inherited a client with a PEPLink routerGS-B20, Firmware 7.0.0 build 3310.
The prior admin had the client configured via DYNDNS for remote access. The Dashboard shows an internal IP address on WAN 1 as 192.168.0.2 which is the windows server (non domain mode). We had some level of corruption that it will not handle DNS correctly on that address. I changed the server address to 192.168.0.4 and it fixed the issues on the server. However, I cannot find where to change that IP address of 192.168.0.2 to the new .4 address to re-enable remote access. I have no experience with this device and client has now been down for a day. Trying to track down the DNS issue on the server with old .2 address not viable and the .4 change fixed all issues.
How do I get it to change to the new server address so that it can properly route to the new server address when coming in via DYNDNS. No other changes to the environment either on the server, PEPLink or DYNDNS have been made other than updating the DYNDNS WAN address after ISP made a change. Device had been working fine until 2 days ago.
