[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [MirageOS-devel] Problem http reply with mirage-static and mirage-www
Hi,
Is anyone else experiencing problems with the mirage-static or mirage-www (env
DHCP=true) on the xen backend, to reply http requests from a network element
other than the host?
Interestingly, when curl from the host the unikernels reply as expected and I
can fetch the home page.
Please find below the wireshark capture if it helps, thanks.
