i have just downloaded firewall builder to use with a linksys router with
the sveasoft firmware.
i can successfully upload firewall scripts using fwb.
for 99% of surfing, all's ok. but for a couple of sites, i'm having some
i think it has to do with my firewall configuration.
i've been reading your cookbook & examples, and i've gotten myself very
can someone provide some guidance?
my situation is:
connected to internet over PPPoE connection to pbi.net
pbi.net <http://pbi.net>, my IP configuration is:
A.A.A.11 usable, rdns --> my.fqdn1.com <http://my.fqdn1.com>
A.A.A.12 usable, rdns --> my.fqdn2.com <http://my.fqdn2.com>
A.A.A.13 usable, rdns --> my.fqdn3.com <http://my.fqdn3.com>
A.A.A.14 usable, rdns --> my.fqdn4.com <http://my.fqdn4.com>
A.A.A.15 usable, rdns --> my.fqdn5.com <http://my.fqdn5.com>
A.A.A.17 reserved, gateway
internal lan is nat'd
router's internal IP is 10.0.0.1 <http://10.0.0.1>
internal DNS SERVER is 10.0.0.50 <http://10.0.0.50>
internal MAIL SERVER is 10.0.0.51 <http://10.0.0.51>
my workstation is 10.0.0.100 <http://10.0.0.100>
external world 'sees' my mail server & dns at A.A.A.11
with all these static IPs, what should be the NAT rules?
currently i have,
with 'Outside' defined in my firewall on the ppp0 interface for all eight o=
the external IPs above.
and i think i just answered my own question .... with your sites' help.
apparently the problem was the mtu setting.
'clamping it' as instruction here say:
fixes all problems with web sites that i have.
i can't say that i understand what the problem is, but the solution works.
