My local network firewall here?

When I nmap my remote server I get these filtered results: 25/tcp filtered smtp 130/tcp filtered cisco-fna 131/tcp filtered cisco-tna 132/tcp filtered cisco-sys 133/tcp filtered statsrv 134/tcp filtered ingres-net 135/tcp filtered msrpc 136/tcp filtered profile 137/tcp filtered netbios-ns 138/tcp filtered netbios-dgm 139/tcp filtered netbios-ssn 445/tcp filtered microsoft-ds 3128/tcp filtered squid-http 4444/tcp filtered krb524 6881/tcp filtered bittorent-tracker 6969/tcp filtered acmsoda So that all must be filtered by my ISP (Cox)? > I recommend you use 587 (right?) the smtp submission port, with sasl > authentication, and ssl if possible. What about your openvpn suggestion? That would get around this problem right? Plus it's a generally good practice? Thank you very much for all your help, and I'm going to get back to that other thread now. - Grant -- gentoo-user@lists.gentoo.org mailing list
