Hello all, I've a SuSE 8.0 installed as firewall for my internal network. Due to my ADSL permanent connetion, I have in mind to "export" on internet http and ftp services. All seems to work good, but I can reach my ftp (or http) server only once from the internet (from a remote internet connection).When I close the remote connection, in the way to get another connection I must restart SuSEfirewall. Otherwise there is no way to reach my servers. In the internal network everything is still working well under any circumstace... May be I take some mistake in the configuration, but I'm not able to find were.... May some one help me? Thank you in advance and sorry for my relative english!
