Catch 22 - VPN Kill - DNS Can't Recover

[4o4rh]

I have

• enabled two VPN connections with Tier1, Tier2 gateway failover config
• DNS Resolver set to use only the VPN connections for forward requests

Scenario 1 - "Skip rules when gateway is down" not checked

• still able to do DNS resolution and browse (despite HTTP rule explicitly selecting VPN gateway)
• summary, not the desired effect

Scenario 2 - "Skip rules when gateway is down" checked (test with single VPN enabled)

• droping VPN neither DNS nor IP browsing works
• summary, desired effect

Scenario 3 - "Skip rules when gateway is down" checked (test with two VPNs enabled)

• drop VPN1 - DNS and IP browsing works
• VPN1 up and then drop VPN2 - DNS and IP browsing works
• VPN 2 up and then drop VPN1 - DNS and IP browsing works
• drop VPN2 (so both VPNs down) - DNS and IP browsing does not work (desired effect)
• re-establish one or both VPNs - DNS and IP browsing does not work (NOT desired effect)

Problem

• seems when both VPNs are down, rules are removed per check box
• when re-establishing the VPN after complete failure, the DNS no longer works - even if resolver is restarted
• this means a reboot is required to restart everything

** i might add, trying to go into status resolver after restarting resolver, hangs

Is there a way to regenerate the rules for a gateway that goes down upon re-establishment to avoid having to do full reboot?
