Cannot access web www.reportviewerplus.com on fresh install on multiple instance

[Nemus]

so no one on our network for some strange reason can access http://www.reportviewerplus.com/

if I put a computer on the public network with a public ip I can get to the site
but if I try to use pfsense I cannot access the site

I did a fresh install of rc2 and did basic nat and still cannot access the site

all others work fine

any idea on what could becausing the issue

@nemus

i have an old pf2.0 beta4 running at home and can't open that site either …. it seems to work if i access by using an external public proxy

I was unable to get to this site either.  I checked the below box and was able to pull up the site.

System: Advanced: Firewall and NAT

Clear invalid DF bits instead of dropping the packets
This allows for communications with hosts that generate fragmented packets with the don't fragment (DF) bit set. Linux NFS is known to do this. This will cause the filter to not drop such packets but instead clear the don't fragment bit.

Yup was having the same issue with that site, then check the invalid DF box as vinsomething suggested and bam site came right up.  Odd, have never seen that before – they clearly has something jacked up it would seem.

yep the issue was DF fixed it
thank you
