Hi

I have another question. I want to publish web site by reverse proxy. But problem is, that this site is accessible by site to site VPN. From LAN site works perfectly, but directly from Barracuda device is unavailable. I try to add route and firewall rule for this site but, it didnt work. But it is possible, that I use wrong parameters....

You may need to create a new Host Firewall rule which correctly does Source NAT to your firewall's internal IP address. It is possible for the default rules cause routing lookups for IPs which are reachable via a site-to-site VPN to suggest using your Internet connection instead which generally ends up with RFC1918 traffic exiting via a public Internet link and then being dropped by the ISP.

Could you give me any hint, how the rule should looks ? I create many rules in host firewall, create many routes in network, but with no sucess. I cant acces remote site from device (localhost). Mainly, traffic route to world, some time it end as bad route
