Guys, I've been performing some work to configure VPN's on a Smoothwall firewall and come up against an interesting issue.
The firewall concerned is connected to the Internet via an ADSL link. Whenever the ADSL link dies, and is restarted, some process within Smoothwall does an echo 1 > /proc/sys/net/ipv4/ppp0/conf/rp_filter. Now this is not a "bad-thing"(tm) in-and-of itself, but it apparently plays havoc with FreeS/WAN. Does anyone know where Smoothwall is setting rp_filter on for the PPP interface after a PPP session is established? -- Rebecca Richards, CCSA CCSE, Security Consultant, e-Secure Pty Ltd "Secure in a Networked World" Phone: (02) 9438 4984 Fax: (02) 9438 4986 Grnd Floor, 71-73 Chandos St Mobile: 0412 823 206 St Leonards NSW Australia Email: [EMAIL PROTECTED] ACN 068 798 194 http://www.e-secure.com.au -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
