I am not sure it's related to centos that much, when it comes to port forwarding, if you might use iptables correctly with several NIC(s), if you can create a vlan with your linksys, like they talk about here: http://www.dd-wrt.com/phpBB2/viewtopic.php?p=4692 I would configure a DMZ pool for the laptop usage only, and forward the needed ports correctly towards the end user Network port. this might help you also for your centos iptables configuration : http://www.howtoforge.com/nat_iptables On Wed, Jul 13, 2011 at 11:41 PM, <m.roth at 5-cent.us> wrote: > Timothy Murphy wrote: >> >> I'm running a CentOS-5.6 server, >> which in general runs perfectly. >> My setting is possibly a little unusual: >> ADSL -> Billion 5200S RC modem/router -> CentOS-5.6 HP MicroServer >> -> Linksys WRT54GL router . >> >> My daughter is just visiting me, >> and she has to contact her job using AT&T VPN >> on her laptop under Windows XP. >> >> Unfortunately this does not work on my system >> when connected to the Linksys router by WiFi or ethernet. >> More precisely, the IBM Lotus "sametime" application does not work, >> and she cannot access the IBM Intranet homepage >> which she needs to use company tools and applications. > <snip> > You may have a port closed that, um, damn, it's only been 3 years since I > was using that client, and I can't remember the name, anyway, that it > uses. > > mark > > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos > -- Best Regards, Yonatan Pingle RHCT | RHCSA | CCNA1
