Nimbostratusintelligent SNAT generate errors
Dear all,
I write a iRule as the following:
when CLIENT_ACCEPTED {
if { [matchclass [IP::local_addr] equals $::Uni_class]} {
pool Uni_first_pool
}
elseif { [matchclass [IP::local_addr] equals $::CRT_class]} {
pool CRT_first_pool
}
else {
pool Default_gateway_pool
}
}
when LB_SELECTED {
if {[IP::addr [LB::server addr] equals 11.10.10.254] and [IP::addr [IP::client_addr] equals 10.6.3.4] } {
snat snat_uni_pool
}
elseif {[IP::addr [LB::server addr] equals 11.10.10.254] and [IP::addr [IP::client_addr] equals 10.6.3.5] } {
snat snat_uni_pool
}
elseif {[IP::addr [LB::server addr] equals 10.10.10.254] and [IP::addr [IP::client_addr] equals 10.6.3.4] } {
snat snat_crt_pool
}
elseif {[IP::addr [LB::server addr] equals 10.10.10.254] and [IP::addr [IP::client_addr] equals 10.6.3.5] } {
snat snat_crt_pool
}
else {
snat automap
}
}
however, that genertat some errors when I update with Webgui, just like the picture, I don't know what is wrong, thank you for you help!

Hi,
The error indicates you were using 'snat pool snat_crt_pool'. The command to specify a SNAT pool is snatpool (without a space).
Can you try this if you want to use SNAT pools and automap?when CLIENT_ACCEPTED { if { [matchclass [IP::local_addr] equals $::Uni_class]} { pool Uni_first_pool } elseif { [matchclass [IP::local_addr] equals $::CRT_class]} { pool CRT_first_pool } else { pool Default_gateway_pool } } when LB_SELECTED { if {([IP::addr [IP::client_addr] equals 10.6.3.4] or [IP::addr [IP::client_addr] equals 10.6.3.5]) and \ [IP::addr [LB::server addr] equals 11.10.10.254]}{ snatpool snat_uni_pool } elseif {([IP::addr [IP::client_addr] equals 10.6.3.4] or [IP::addr [IP::client_addr] equals 10.6.3.5]) and \ [IP::addr [LB::server addr] equals 10.10.10.254]}{ snatpool snat_crt_pool } else { snat automap } }

monica_74227thank you very much Aaron, I will try that!- monica_74227hey Aaron,
I have tried that iRule, It should now include the "\", the following is okay :
when CLIENT_ACCEPTED {
if { [matchclass [IP::local_addr] equals $::Uni_class]} {
pool Uni_first_pool
}
elseif { [matchclass [IP::local_addr] equals $::CRT_class]} {
pool CRT_first_pool
}
else {
pool Default_gateway_pool
}
}
when LB_SELECTED {
if {([IP::addr [IP::client_addr] equals 12.10.10.1] or [IP::addr [IP::client_addr] equals 12.10.10.2]) and [IP::addr [LB::server addr] equals 10.10.10.254] } {
snatpool snat_uni_pool
}
elseif {([IP::addr [IP::client_addr] equals 12.10.10.1] or [IP::addr [IP::client_addr] equals 12.10.10.2]) and [IP::addr [LB::server addr] equals 11.10.10.254] } {
snatpool snat_crt_pool
}
else {
snat automap
}
} - hoolioThe backslash just escapes the newline character and allows you to break up long lines. Functionally, you can remove it with no difference.
