You have asymmetric routing because the host is dual homed, which will cause problems with any stateful firewall. You either need policy routing on the host itself to ensure all traffic leaves the same interface it enters via the appropriate gateway when off-subnet, or only use the interface IP where the default gateway resides when off-subnet, and only the local subnet IP when on subnet. Please don't post the same thing to both the forum and mailing list unless you don't have a response on one or the other after 24 hours. --------------------------------------------------------------------- To unsubscribe, e-mail: support-unsubscr...@pfsense.com For additional commands, e-mail: support-h...@pfsense.com Commercial support available - https://portal.pfsense.org
