APM SSLVPN with layered virtual
Hi guys, I'm trying a new (for me), but oftenly recommended by F5 SEs, setup with layered virtuals. In my testing environment, I have only one single IP address. This is used for a standard virtual server, which will be used as some kind of a jump VS (let's call it 'VS_jump'). I've assigned an LTM policy to this VS, which forwards the traffic to different virtuals, based on the requested host header. Basically this is working finde. But I'm struggling arround with APM and SSLVPN (Network Access). The requests hit the correct VS ('VS_apm-sslvpn') with APM profile assigned and the user is able to authenticate. But after opening the PPP tunnel, it's ending in a timeout for the client. The APM log tells me, that the tunnel was directly closed: PPP tunnel 0x56009ef6dd00 (ID: 703c0a5b) started. PPP tunnel 0x56009ef6dd00 (ID: 703c0a5b) closed. This issue only occurs, if the APM profile is bound to the forwarded virtual, 'VS_apm-sslvpn'. For testing purposes I've assigned the APM and connectivity profile to 'VS_jump' and the connection came up directly, without any issue. The message PPP tunnel 0x56009ef6dd00 (ID: 703c0a5b) closed. only appears, when the connection is manually disabled. So my question is: Are there any known limitations to SSLVPN, when used in conjunction with layered virtuals? I'm not sure about settings like HTTP-XFF or SNAT - where shall they be set? On 'VS_jump' or 'VS_apm-sslvpn'. Unfortunately I wasn't able to find anything related to SSLVPN and layered virtuals. Any ideas? Thanks in advance. Cheers, Sven
