Re: Slow VPN speed
I have a Site-2-Site IPsec tunnel setup using 60E. the office are between China, GZ area, and Singapore.
China side access Singapore file server has a download speed of 355KB/s, kind of limited by something. I tried using traffic shaper, no help. then, we do a reverse, access China file server from Singapore, to my surprise, the download speed is 1.15MB/s! Further, I use LTE mobile connection in Singapore with forticlient and access the Singapore file server, I also get a download speed of 355KB/s.
Conclusion is that Singapore side VPN has a limited upload limit. but why?
I found the 60E has different FW version installed in both sites, v5.4.4 build7619 in China, and v5.4.1build5577 in Singapore.
Will v5.4.4.and v5.4.1 make the different?
