Sophos XG 115 / SFOS 18.0.3 MR-3 / Web admin access working locally and through WAN access but not through VPN

armarzook

Dear Community,

The subject itself tells the whole story in brief.

I can locally access the web admin access and also through WAN (public) without any issues,

VPN is working fine and other web server sites published in master site are accessible without a glitch.

Kindly help me to rectify this.

Sophos support advised to change the MTU on the WAN port of XG firewall to which nothing happened.

Looking Forward,

Mohamed Marzook.

    Hi,

    also check the following then:

    • Check that the SSL VPN port and the admin web portal port don't interfere 
    • Create a firewall rule from VPN to LAN
    • If SSL VPN is configured in Split mode, make sure you have added Sophos XG LAN IP in SSL VPN (Remote Access) > Permitted Network Resources 
    • Access Sophos XG through your LAN IP
    • Check the traffic Flow on XG for request for port 4444 > Use Packet capture and see if the traffic is reachable to XG and what action XG has taken.
    • Compress SSL VPN Traffic should be disabled.

    Dear,

    Site A - SonicWALL NSA2600

    Site B - Sophos XG

    VPN type - IPSec

    Working - Everything else

    Not working - Web admin access of Sophos XG on Site A.

    Web admin port - Changed to 20443. So the URL is https://xxx.xxx.xxx.xxx:20443

    Web admin access through WAN using the public IP with the same port is working very well.

    Now tell me what am I missing.?
