DNS over L2TP

JeffCooper
Hi All,

Recently updated from a UTM220 running v8 to a 320 with 9.106-17.  Got it mostly working except we cannot get DNS to work through L2TP over IPSec.  DNS functions fine on the LAN.

We have the LAN and VPN Pool (L2TP) specified under allowed networks in the DNS global tab.  In v8 that seemed to be all we needed to do, but it's not working in 9 (we didn't import settings, we entered them fresh so we may just be missing something).

We made a rule to allow the DNS service from the VPN Pool (L2TP) to All in the firewall settings just in case that was it, but no dice.

Not sure what other info I could post to be helpful.

Thanks,

Jeff

ps. as a workaround for now, we're having people manually enter openDNS servers in their client DNS settings, so it's not a total panic (yet), just really annoying.

    Did you enter your DNS servers in Remote Access -> Advanced?

    Thank you!  We did enter it but I went back to look and found that we had the LAN gateway address specified, not the address used by the VPN. Seems to be working.

    Thanks!
