Site-toSite VPN cannot access XG on remote site using normal 4444 port.

I have set up a iPsec VPN between 2 sites (Site A 192.168.99.x, Site B 192.168.1.x)

The VPN works fine and I can access servers on SITE B from SITE A via RDP connections using local IP's

However If I try to access the XG device at SITE B (https://192.168.1.3:4444) from SITE A it will not connect. - I have also found other connections on SITE B are also not found including the Sophos Firewall Manger device (hardware). I can ping these device with no problem from SITE A -> SITE B - very strange ?

Running ( XG210 (SFOS 17.1.1 MR-1) )

Hi Mark,

Check if device access over HTTPS is allowed for VPN in Administration > Device Access > VPN > HTTPS.

Device Access allows you to limit administrative access to certain services from custom and default zones (LAN, WAN, DMZ, VPN, Wi-Fi).

This is already done. Just fails every time. It seems to be any device on the SITE B Lan e.g NAS drives, Sophos Firewall Manager (typically ones that have a PORT option)

Which device do you use on the other site of the XG tunnel?

Nope - I logged a case with tech support and it has been escalated right up to senior support - I have spent many hours on remote sessions but still no solution !!

It only seems to be when the WAN connection to the ISP is STATIC - if it is PPoe then all works fine.

Hello,

Which IPSEC policy was used? Did you enable data compression?

I had the problem once before. Servers were available. Ping went too but I could not open the web interface of the XG (TLS handshake timeout) and traceroute did not work either.

It can be checked relatively quickly whether you can open the XG with Internet Explorer.

best regards,

Pascal

Hello,

Thanks for your reply.

I use the DefaultBranchOffice Ipsec profile. (and DefaultHeadOffice on my central Sophos XG)

In SFOS16 DefaultBranchOffice IPSec Profile, the compression is ON.

Not in SFOS17.

Do you think I have to test with the compression ON ?

Because in SFOS16, we don't have this Admin Login Page access problem.

Problem is the same with IE or Firefox.

Thanks in advance.

Ludo.
