Hi folks, I am using an openbsd (5.9) box as gateway/firewall to the internet. ISP is Deutsche Telekom. In between is a Vigor 130 VDSL2 modem, configured to PPPoE passthrough. The PPPoE connection is initiated on the openbsd box.
Problem: https via the tunnel gets stuck for some sites, e.g. https://telekom.de/ (please note the irony). Other sites work fine, e.g. https://kundencenter.telekom.de/. I tried a lot of clients: chrome, firefox, Safari, wget, etc. and all platforms I have at home. Other services (http, smtp, dns, ntp, vnc, ...) seem to work flawless. The problem came up with the migration from ADSL to VDSL this weekend. The gateway wasn't changed, but I wonder if there are some issues or pitfalls with PPPoE and fragmented packages or whatever, possibly breaking https negotiation? Every helpful comment is highly appreciated Harri
