|OS type and version||Centos7 and Ubuntu 20|
Still trying to figure this one out and its driving me nuts.
I have 2 servers, one Ubuntu and one Centos. One is a Linode shared server the other is running on its own IP from my home. Both have the latest webmen/virtualmin setups.
I asked this same question on the Authentic Theme group:
The connections to webmin work fine when I am not using a VPN. As soon as I go through my VPN to the server the connection slows to a crawl. With Authentic Theme my connection usually times out or may finally display after an hour or so. By switching to the old Virtualmin gray theme I can make a connection and actually use the webmin connection (although it is still very slow.) For my Linode server I could just ignore my VPN and everything will be fine but my home server has a NAT hairpin? issue that makes it so I can only get to that server if I use a VPN. The actual sites on that server do not suffer from the VPN slowdown, only the Webmin server.
I get 2 IPs from my ISP at my home. My server uses one of those and my home network uses the other. From my home laptop (IP 1) I can not access the server (IP 2) unless I go through a VPN. I have not been able to figure this out but have been told that it has something to do with a NAT hairpin turn that the particular modem cannot handle. I therefore need Webmin to be accessible going through a VPN. At the moment that does not appear to work well.
If this was only happening on my local server I would assume it is a local issue but since it does not work with my 2nd server which is not on my home system there has to be another problem. I just can’t figure out what it is.
Any suggestion on how to solve this?
