Hello Dag,

Yes i ha= ve tried to add static route for the remote subnet in the tab of

doesnt re= solve DNS, however i can ping to DNS IP but it's not resolving.

= So here is my complete scenario:

1- Create a VPC and create a Tier.<= br>2- I go to my router and everything works fine on router and tier as wel= l.
3- I can see =C2=A0default route is my public gateway.
4- i also c= an see 4 interface, one for public, one for link local, one
for Tier and= last for loopback.
5- then i add a private gateway, and i can see that = one more interface
is also added in router.
6- I check on my router ,= everything looks good, internet is working ,
DNS is also resolving on r= outer and tier as well.
7- when i reboot my router, everything is stoppe= d working.

i also compared my iptables pre-reboot and post reboot, = some changes
has been made in iptables post reboot so it might be a caus= e,

Any idea Dag ?
