having trouble with the PIX firewall stripping the TCP options as traffic passes through. We have Citrix WAN scalers that use these options to accelerate TCP connections.
Can any one advise of the syntax to do this?
Does anyone know if PIX v7 command syntax differes from PIX v6 ?
I have command syntax for v7 below, but this does not seem to be accepted on our PIX 6 firewall.
pixfirewall(config)#access-list tcpmap extended permit tcp any any
pixfirewall(config)# tcp-map tcpmap
pixfirewall(config-tcp-map)# tcp-opt range 24 31 allow
pixfirewall(config)# class-map tcpmap
pixfirewall(config-cmap)# match access-list tcpmap
pixfirewall(config)# policy-map global_policy
pixfirewall(config-pmap)# class tcpmap
pixfirewall(config-pmap-c)# set connection advanced-options tcpmap
Thanks again guys!!
Solved! Go to Solution.
can i please have some advice on this...?
has no one come accross this kind of problem before?
Does any one know whether TCP policy mapping can be done on PIX v6.0?
Please see the other replies on this, but no there is no way to do policies like this in 6.X like there is in 7.X. For us, it was not needed in 6.X, it just worked. We did require the change on the 7.X side.
We just ran into this exact problem today. One wanscaler was behind a PIX 6.3 firewall, and the other behind an ASA with version 7.X.
We found that the version 7 needed the above configuration, but the version 6 did not.
I could not find anywhere to set TCP Options in a PIX 6.X firewall. But as soon as we did the config on the 7.X firewall, it immediately started working end-to-end.
There is a difference between Pix 6.x and 7.x. In Pix 6.x. all TCP options should pass unchanged. But, in Pix 7.x, you need the above commands to make Citrix work.
