I got a ubuntu server running redmine from apache.
My clients, can access redmine, but stops responding random, and other clients, can browse redmine fine, when the client with the problem cant browse the page.
In tcpdump i see the request come in, but nothing goes back to the client, its the same with icmp packges
I have tried to ping the other way (server -> client) and it the client returns a response.
Has anyone a solution or some experiences with that problem?
