Re: [LARTC] bgp require in multigateway routing
somebody suggest me to use border gateway protocol for this, but i don't have any knowledge about this protocol that it will useful for me our not, and plz also guide me how to configure this protocol. considering the bandwidth, i dont think your ISP would even start to think about BGP, not to mention the fact that as long as you use the same ISP I'd rather think of OSPF or even RIPv2. Also, there is a question of support on modem, as from what you say its actually a router with adsl modem integrated, so it should take part of dynamic routing. All in all, first question to ask is what your ISP is willing to do in this case. As an alternative you can always run some checks on links and switch routing information (aspecially default route, or selection of routing table in policy routing) in static table from some cron script / daemon accordingly. -- Radek aka Goblin [EMAIL PROTECTED] ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
Re: [LARTC] PAT HOW to - IPTABLES
Suppose, I have 3 mail servers @ DMZ zone with one real ip. the situation as before? in that case, What can I do? your could use exim/postfix and route the mail to the right server, but I guess you are trying to find out how to have port 25 on the real ip nat'ed to one of the 3 dmz'ed ip based upon the destination mail address short answer you can't as far as I know, iptables only looks at src ip / src port dest ip/dest port. You could write your own plugin module to look into the tcp stream. based upon destination email address/domain could be done by postfix and transports for selected mail/domain to selected server. but there is also a possibility of load balancing and failover for set of domains with all servers working with all the domains for HA and flexibility of computing power, then id say take a look at keepalived for both those features. for http traffic its actually the same, and also you can consider apache reverse proxy feature. -- Radek aka Goblin ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
Re: [LARTC] optimizing traffic to a web server
kamen pisze: Hi, I have a Linux server and provide Internet access in the neighborhood and I also run a web server on the same machine. Although our external connection is not bad, the access to the web server from outside is awful - the web pages always require Try again when accessed. Do you think I can prioritize the traffic to the web server? How? I have a traffic shaper of the internal and the external interface. I use tc with HTB and iptables for that purpose. I mark the packets and then filter them. I just don't seem to have written the write filters. Thanks in advance! this task should be an easy objective to acomplish, do you have some kind of shaping in place at this moment ? anyway, please supply more info on priv and i may be able to help you. -- Radek 'Goblin' Pieczonka [EMAIL PROTECTED] ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
