Hello,
i have a software appliance which is running UTM 9.105-9. Today, i replaced the network card (single port, internal lan) with a dual port nic. i tried to separate internal LAN and VoIP devices.
everything is fine, the new nic (Intel Pro 1000MT) is online and configured, and the UTM settings look fine. But i have a strange problem: the internal LAN port 1 of the dual port nic) is working properly and can access the internet and vice versa. but the VoIP devices behind port 2 cannot access the internet. the UTM is pingable, dns requests are working properly, the UTM WebAdmin can be accessed, but no internet. The problem persists with an any-any-rule. I can view the connection attempts to the internet in the live monitor (green = allowed), but it simply doesn't work.
So i tried to ping my internet server (outside my network) while running tcpdump on it. It does not receive a single ping, but the UTM reports in the live log, that the request was allowed...
any ideas ?
